前文已报导了具有较好抗凝血性能的新型聚电解质,聚甲基丙烯酸己磺酸钠(PSSH-MA)的合成,用统计方法对盐存在时PSSHMA溶液的粘性研究及用小角激光光散射法测定的PSSHMA体系的特性粘数和重均分子量的关系。本文进一步用KNAUER膜渗透计测定了该体系的特性粘数与数均分子量的关系,并进一步探讨聚电解质水溶液渗透压测定中的一些问题。
The synthesis of PSSH-MA, a novel polyelectrolyte with good anticoagulant properties, has been reported previously. The viscosity of the PSSHMA solution in the presence of salt and the viscosity of the PSSHMA solution using small-angle laser light scattering Relationship between intrinsic viscosity and weight average molecular weight of PSSHMA system. In this paper, KNAUER membrane osmometer was further used to determine the relationship between intrinsic viscosity and number average molecular weight of the system, and to further investigate some problems in the determination of the osmotic pressure of polyelectrolyte aqueous solution.
