| 摘 要： | 通过氧阴离子聚合合成了一系列不同相对分子质量的结构明确的BzO—PDMAEMA，用芘作为荧光探针研究了BzO—PDMAEMA在水溶液中的胶束化行为，发现CMC值与用表面张力法测得的结果相一致，即随BzO—PDMAEMA相对分子质量的增加而减小，但荧光探针法测得的CMC值稍大；LCST值则随相对分子质量的增加而增加。

| Abstract: | Pyrene was used to investigate water solution properties of a series of well-defined benzyloxy-capped poly2-(N,N-dimethylamino)ethyl methacrylate](BzO-PDMAEMA),which were synthesized by using potassium benzyl alcoholate as initiator via oxyanion-initiated polymerization.The results showed that the values of CMC decrease with the molecular weight,which is identical to the results measured by surface tension method,and LCST increase with the molecular weight. |
