摘要
本文在旋转异构态模型下 ,导出高分子链构型参数理论公式 ,计算了聚丙烯酸甲酯链的特征比随分子量和链规整性变化的规律 .并通过比较聚丙烯酸甲酯、聚苯乙烯和聚甲基丙烯酸甲酯链的计算结果 。
The characteristic ratio of unperturbed mean\|square radius of gyration \%〈S\+2〉\-0/2xl\+2\% of poly (methyl acrylate) chain, as a function of the molecule weight and the tactic, was investigated by the rotational isomeric state theory. The estimated results for poly (methyl acrylate), polystryene and poly (methyl methacrylate) chains can describe the relation of the intrinsic viscosity with the tacticity.
