Determination of Some Physical Properties parameters of polymers by Structure Unit Contribution Method Using Microcomputer

本文用微机按结构单元贡献法测算了聚合物的某些重要物性参数.诸如:比容 V_p、溶解度参数δ、玻璃化转变温度 T_g 和缠结点问分子量 M_e.33种结构单元的性能存贮于计算机内,可以随时调出用以构造所要求的聚合物重复单元中的主链与侧链结构,然后由计算机程序计算聚合物上述4种物性参数.

In this article,several imporlant physical properties parameters of polymers,much as specific volume Vp,solubility parameter δ,glass transition temperature Tg and molecular weight between entanglements Me, all of these have been determined by structure unit contribution method using microcomputer.The properties of 33 structure units are stored in computer memory and at all times being recalled to construct the main chain and side chain structures in the desirable polymer repeating unit.Then the above four physical properties of polymers can be calculated by computer program.
