In this section, the drop functions for PR are derived. The courage of the drop functions consists of two parts: the Kratky–Porod worm-like alternation model18 acquired by Yamakawa and Yoshizaki,19 and the accidental copolymer archetypal acquired by Endo and Shibayama.20 The worm-like alternation archetypal is a acceptable archetypal for actual annealed polymers, area the alternation amid the two band vectors and decays exponentially as with the breadth of the band agent l and the alternation breadth lp. This archetypal should be applicative to semiflexible PR. The alternation arrangement of PR, which affects the drop ambit in a high-Q range, is indispensable; however, it can be about congenital into the drop action as declared below. It is all-important to accede the three altered drop contributions individually, namely, two self-correlations of the axial polymer and the beaded circadian molecules and the cross-correlation amid the arbor and the beads. We will abridge the worm-like alternation archetypal and the accidental copolymer archetypal first, afterwards which the drop functions for the beads, the arbor and the cross-correlation will be acquired one by one.

The worm-like alternation archetypal acquired by Yoshizaki et al.19 is an empiric blueprint aing the Debye action for a Gaussian alternation at low Q and the anatomy agency of a rod at aerial Q in continuity; that is with the consequence of the drop agent Q (=4π sin(θ/2)/λ; drop bend θ, amicableness of adventure axle λ), curve breadth L and alternation breadth lp. The changeless articulation (Kuhn) breadth b is accompanying to the alternation breadth by lp=b/2. The Debye action PDebye(Q, L, lp) is authentic as area u=Rg2Q2, with the ambit of ambit of the beeline polymer Rg accustomed by
The anatomy agency PRod(Q, L) in Blueprint (2) is accounting as with the sine basic . The cross-over arena amid PDebye(Q, L, lp) and PRod(Q, L) in Blueprint (2) is adapted by functions χ(Q, L, lp) and Γ(Q, L, lp). The agency χ(Q, L, lp) is accustomed by and Γ(Q, L, lp) is bidding as a action of Q, L, lp and 35 coefficients afflicted by Yoshizaki and Yamakawa.19
The accidental copolymer archetypal of blazon A–B was acquired by Endo et al. on the base of Gaussian statistics.20 In the case of a beeline accidental copolymer with monomer-A and monomer-B, the fractional drop action of monomer-A is declared by discretization of the Debye action with breach l0 as area N is the articulation cardinal (that is, N=L/b) and n0 is accompanying to the breach l0 as l0=N/n0. In this definition, l0 × lp corresponds to the breadth of a distinct monomer unit. Am/n(k) is an n0-dimensional agent authentic by for the kth interval. The ensemble boilerplate is with the breadth atom of monomer-A basic ΦA.

In the case of a absolutely accidental action for the administration of monomers, Am(i)·An(j) in Blueprint (7) can be commissioned by
; then, an ytic anatomy of Blueprint (7) is acquired as with x=Q2Rg2 and N=1 (1−ΦA)/(ΦAn0).
The drop acuteness I(Q) of PR in band-aid is accustomed by area C and P announce circadian molecules and the axial polymer in PR, respectively. Δρi (i=C, P) is the drop adverse amid component-i and the solvent, that is, Δρi=ρi–ρS with the drop breadth densities of component-i, ρi and that of the solvent, ρS. Sij(Q) denotes the fractional drop action in PR, namely, SCC(Q) and SPP(Q), which represent the intracorrelation of circadian molecules and the axial polymer, respectively; SCP(Q) expresses the intercorrelation (or cross-correlation) amid circadian molecules and the axial polymer. In Figure 1, a conceptual adjustment of the fractional drop functions is illustrated. Derivation of anniversary Sij(Q) will be declared beneath after because the intermolecular interaction.

The fractional drop action of the axial polymer, SPP(Q), can be approximated by the worm-like alternation archetypal accustomed by Blueprint (2): area nPR is the cardinal body of PR and VP is the aggregate of the axial polymer.
For the description of the fractional drop action of circadian molecules, SCC(Q), we charge to accommodate the accidental copolymer archetypal into the worm-like alternation model. The affinity can be agitated out with barter of Blueprint (7) for Blueprint (3); at the aforementioned time, the anatomy agency of a rod accustomed by Blueprint (5) charge be replaced by
See Equations (A6) and (A7) in Appendix A. Finally, SCC(Q) is accustomed by area VC is the absolute aggregate of the circadian molecules threaded on the distinct axial polymer. χ(Q, L, lp) and Γ(Q, L, lp) in Blueprint (14) are afflicted to be identical to those accustomed by Yoshizaki and Yamakawa.19 In the accident that the circadian molecules administer about on the axial polymer, the ytic forms accustomed by Equations (10) and (A8) can be used.
The intercorrelation amid circadian molecules and the axial polymer, SCP(Q), can additionally be afflicted with the worm-like alternation model; that is, SCP(Q) can be declared as area and with area An(j) authentic by Blueprint (8) represents the anticipation body of the axial polymer, that is, An(j)=1 for any j. Furthermore, by d that circadian molecules can locate appropriately at any armpit in the axial polymer, we can alter Am(i) by its ensemble boilerplate
. In this case, is obtained, area PCP(Q) can be simplified as
As discussed in the aloft section, the fractional drop functions, SCC(Q) and SCP(Q), can reflect the row of circadian molecules on the axial polymer. The administration of circadian molecules on the axial polymer can be evaluated by quantitative yses of SCC(Q) and SCP(Q) application Monte Carlo simulations.
To investigate biased alignments of the circadian molecules, we ascertain the codicillary anticipation that two circadian molecules are successively placed as φcc and the codicillary anticipation that two circadian molecules are not successively placed as φc. By defining the absolute breadth atom of the circadian molecules as Φc, we can chronicle Φc to φcc and φc as follows:
In the model, Φc>φcc indicates a abhorrent alternation amid circadian molecules, and Φc <φcc indicates an adorable alternation amid circadian molecules. The Monte Carlo simulation for SCC(Q) can be performed by application Equations (8) and (14), area Am,n(k) is accustomed by and area φk is a generated accidental cardinal amid 0 and 1. In this simple model, however, the accepted amount for Am(i) is constant, apart of φcc and φc. In added words, the ensemble amount <Am(i)> is consistently connected for any ethics of φcc and φc so that SCP(Q) cannot be afflicted by the adjustment of the circadian molecules. Therefore, it is alone accessible to access advice about the arrangement of circadian molecules by allegory SCC(Q) with this method.
By abbreviating the absorption of polymers in solution, the polymers gradually alpha to overlap anniversary added aloft the overlap absorption c*. In the accident that the absorption of the polymers is far beneath c*, the changeless drop intensities I(Q) can be declared with the anatomy agency Ppoly(Q): area I0 is the advanced drop intensity, which can be afflicted as I0=n × V2 × Δρ2 with the cardinal body of the polymer n, the aggregate of the polymer V and the drop adverse amid the polymer and the bread-and-er Δρ. If the absorption of the polymer is in the around of c*, Blueprint (24) is invalid because of the aftereffect of interpolymer interactions. The Zimm blueprint treats the interpolymer alternation with the additional virial accessory A2, which is accustomed by area M is the atomic weight of the polymer, and c is the mass-concentration of the solute. For polymer solutions, A2 can be accompanying to the afar aggregate ν as with Avogadro’s cardinal NA and the molar accumulation of the monomer, m.

Equation (25) was originally acquired with distinct acquaintance approximation and an acceptance that 2A2Mc is actual baby compared with unity;21 therefore, the applicative absorption should be rather diluted. In fact, the announcement accustomed by Blueprint (25) has been accepted to be accurate at abundant college concentrations theoretically,21 and we accept additionally experimentally accepted its authority in PR solutions.16
The Ornstein–Zernike (O-Z) blueprint is additionally about activated for semidilute polymer solutions, area I(Q) ∝ (1 ξ2Q2)−1 (with the alternation breadth ξ);22 however, it has been experimentally accepted that the O-Z blueprint does not fit PR solutions able-bodied because of the appreciably ample alternation breadth and arrangement of PR.16 Therefore, Blueprint (25) will be accumulated with Equations (12), (14) and (19) to assay the fractional drop functions quantitatively.
