摘要

本文主要介绍了聚合物性能预测的两种方法:基团贡献法和连通性指数法。本文阐述了该方法的基本原理、仿真方程及其应用。用基团贡献法模拟了一些聚合物的比容、溶解度参数、玻璃化转变温度和缠结点之间的分子量，得到了较好的结果。并以聚氯乙烯为例详细说明了连通性指数法的过程，取得了较好的结果。

Prediction of Polymer Properties

This paper mainly introduced two methods about prediction of polymer properties: group contribution method and connectivity index method. The base principles, simulation equations and applications were explained in this paper. The specific volume, solubility parameter, glass transition temperature and molecular weight between entanglement point of some polymers were simulated by group cotribution method and got better results. Moreover the process of connectivity index method were illustrated with example of PVC in detail and got better results, too.
