A process for preparing defined molecular weight polymers, particularly polyquaternary ammonium compounds, is disclosed. As the molecular weights of these compounds can be absolutely defined, rather than defined merely in terms of "number average molecular weight," these compounds are particularly useful as identification standards for other polymers which are made using conventional polymerization processes. The polyquaternary ammonium compounds described are further suitable for use as antimicrobial agents, particularly in ophthalmic compositions.
本文公开了一种制备定义分子量聚合物的方法,特别是聚季
铵盐化合物。由于这些化合物的分子量可以绝对定义,而不仅仅是以“数均分子量”来定义,因此这些化合物特别适用作为使用传统聚合过程制备的其他聚合物的标准。所述的聚季
铵盐化合物进一步适用于用作抗菌剂,特别是在眼科配方中。
