利用流变仪测定聚苯乙烯的分子量和分子量分布的研究

Study on Molecular Weight& Distribution of Polystyrene by Meansof Advanced Rheology Expanded System

摘要: 用先进流变扩展系统ARES（Advanced Rheology Expanded System）对聚苯乙烯的分子量和分子量分布进行了测定，并且将所得的结果与GPC的结果进行了比较，发现误差非常小. 因此认为用ARES进行特定聚合物的分子量及分子量分布测定，是一种快速、准确的测定方法，对生产的质量控制有一定的帮助.

Abstract: Molecular weight and distribution of Polystyrene were tested by means of Advanced Rheology Expanded System(ARES), comparing with the results of GPC. The results showed that errors were lower. This method was very easy and quick, some helpful guidance on quality control of process has been provided.
