易挥发溶剂中高聚物分子量的测定

Determination of the polymericular weight in the easy volatile solvent

提出一种测定仅溶于易挥发溶剂中的高聚物分子量的方法和粘度计，测定了聚苯乙烯、聚甲基丙烯酸甲酯、氯丁橡胶等高聚物的粘均分子量．

A new viscorneter and method for determination of the polymericular weight in the easy volatile solvent has been proposed. Using this method, the viscosity-average molecular weight of polystyrene, polymethacrylate and polychloroprene are measured. Determination results shows that the new method not only guarantees accuracy of determination but also is simple in operating.
