Statistical and metric properties of long-chain combs

Abstract: Computer simulation results on statistical and metric properties of long-chain combs are presented. The branches in the comb contain a fixed number of segments and are regularly placed along the backbone such that their number increases linearly with the total number of segments. Three cases have been studied, representing three ratios for the number of segments per branch relative to the number between branch points. Comparison of g(=(S2).-J < S2) saw, where (S2 > represents the mean-square radius of gyration… Show more

“…Recent simulations the distribution coefficient of combpolymers show deviations between SAWs and RWs [15] . The deviations between the simulated branching ratios, g, of Gaussian chains and self-avoiding walks have also been found by Lipson [17,18] and Radke [19] . In order to compare the simulated g-ratios with the experimental data, a variety of star polymers were synthesized and investigated by conventional and GPC-light scattering.…”

“…More accurate results are obtained from Monte Carlo simulations and other numerical techniques [70][71][72][73][74][75][76]. The principal idea is to measure the size and molecular weight of a BP using experimental techniques such as SEC, light scattering, or intrinsic viscosity (Mark-Houwink plots), and so forth, and then use the available g-ratios to determine the nature and degree of branching.…”

“…Furthermore, while the overall dimensions of the comb are reduced relative to that of a linear chain of the same number of segments, the backbone is expanded when the self-avoiding condition is incorporated. 46 Those results suggest the need to explore the span dimensions of self-avoiding combs and other branched architectures including stars and two-branch-point polymers of many arms. We will return to this discussion in section 4.…”
