Abstract

The present work continues our previous studies of pom-pom molecule [K. Haydukivska, O. Kalyuzhnyi, V. Blavatska, and J. Ilnytskyi, J. Mol. Liq. 328, 115456 (2021); Condens. Matter Phys. 25, 23302 (2022)]. The molecule consists of a linear backbone with two branching points at both ends, with functionalities f1 and f2. Here, the main attention is concentrated on studying the impact of the central backbone length on the configurational charactersitics of complex molecule, such as size and shape ratios. We apply both a direct polymer renormalization scheme based on continuous chain model and the alternative Wei's method to analyze a set of size and shape properties of pom-pom polymers in dilute solution. The size ratio of a pom-pom and a chain polymer of the same total molecular mass is calculated with an excluded volume interaction taken into account, and estimates for asphericity are found in Gaussian approximation, whereas for the size ratio we found a monotonous dependence of the length of backbone at different functionalities of side arms. Results for asphericity show a non-trivial behaviour.
绒球聚合物的溶胀性能:主链长度的影响
本研究延续了我们以往对弹珠分子的研究[K]。张建军,张建军,张建军,等。中国生物医学工程学报,2003,19 (4):481 - 481;提供者。物质物理学报,25,23(2022)。该分子由两端有两个分支点的线性主链组成,官能团为f1和f2。在这里,主要关注的是研究中心骨架长度对复杂分子构型特征的影响,如大小和形状比。本文采用基于连续链模型的直接聚合物重整方案和替代的Wei方法,分析了稀溶液中软球聚合物的一组尺寸和形状特性。在考虑了排除的体积相互作用的情况下,计算了具有相同总分子质量的弹球和链状聚合物的尺寸比,并在高斯近似中发现了非球面性的估计,而对于尺寸比,我们发现了侧臂不同官能团的骨干长度的单调依赖。非球面的结果显示出非平凡的性质。
