manner leading to narrow molecular weights distribution. Amphiphilic copolymers were finally obtained after complete or partial hydrolysis of the PtBA blocks into PAA. The control of the partial hydrolysis of tBA units, conducted in a concentrated HCl/tetrahydrofuran mixture, is demonstrated. The properties of the triblock copolymers were preliminary investigated in aqueous solution by absorbance, DLS
由聚(丙烯酸)(PAA)和统计聚聚合物[(丙烯酸) -共- (叔-butylacrylate)](P(AA-共-吨BA)),附连到的Jeffamine的两个末端(d系列本文介绍了使用基于原子转移自由基聚合(ATRP)的聚环氧丙烷(PPO)(在每个末端具有一个胺官能团)的聚合物。最初由Jeffamine®精制了一种基于双功能酰胺的大分子引发剂。吨BA聚合随后从该大分子引发剂引发。这种聚合反应受到良好控制,导致分子量分布狭窄。P t完全或部分水解后,最终获得两亲共聚物BA进入PAA。证明了在浓HCl /四氢呋喃混合物中进行的t BA单元部分水解的控制。通过在水溶液中通过吸光度,DLS测量和SEC / MALS / DV / DRI分析对三嵌段共聚物的性能进行了初步研究,这些温度和pH值随其变化而变化,为共聚物对温度和pH敏感的自组装提供了证据。 。©2015 Wiley Periodicals,Inc
