本文报导了有规立构聚苯乙烯,无规立构聚苯乙烯和1∶1混合有规和无规立构聚苯乙烯的分级、粘度和光散射测试结果。发现上述三种聚苯乙烯试样的[η]-M的依赖关系、第二维利系数和均方末端距(当分子量相同时)是有差别的。这种差别超出实验误差范围,而作者们认为是合理的。从而讨论了前人在类似的工作中所得到的结果。 This paper reports the results of fractionation, viscosity and light scattering measurements of stereoregular polystyrene, atactic polystyrene, and 1: 1 mixed, atactic and atactic polystyrene. The [η] -M dependence of the above three polystyrene samples was found to be different from the second Vernier coefficient to the mean square end distance (when the molecular weights are the same). This difference is beyond the experimental error range, and the authors consider it reasonable. Thus discussing the results obtained by predecessors in similar work.
