A Study of Configuration and Conformation Statistical Properties of Polyitaconate Chain

利用旋转异构态模型和伪立体化学平衡统计方法,得到考虑侧基的均方回转半径及温度系数的改进公式,研究典型的大侧基聚衣康酸酯链的构象和构型性质.并通过数值计算,研究无规聚衣康酸酯链均方回转半径特征比、温度系数与构象能的关系,研究链规整程度对均方回转半径特征比的影响.

The improved calculations of the mean-square radius of gyration and its temperature coefficient are developed to study the configuration-conformation statistical properties of polyitaconate with the large side groups based on the rotational state scheme and the pseudostereochemical equilibrium method. The dependence of characteristic ratio of radius on conformational energy for atactic polyitaconate chains is numerally calculated, and the effect of tacticity of polyitaconate chain on unperturbed bimension and temperature coefficient are investigated in this work.
