addition–fragmentation chain transfer (RAFT) polymerization. 2-Methyl- and 2-ethyl-2-oxazoline were polymerized for the POx block via CROP, and methyl acrylate, methyl methacrylate, N,N-dimethylacrylamide, N,N-diethylacrylamide, N-isopropylacrylamide, and 4-acryloylmorpholine were polymerized for the other block via RAFT polymerization. The CROP and RAFT polymerization proceeded independently in a controlled
作为嵌段共聚物轻松快速一步合成的第一个例子,在微波辐射下,一步一步合成了一系列基于聚(2-恶唑啉)(POx)的嵌段共聚物,大大缩短了合成时间。使用4-氰基-4-(十二烷基硫代羰基硫代硫基硫基)戊基-4-甲基苯磺酸酯(CDPS)作为活性阳离子开环聚合(CROP)和可逆加成-断裂链转移(RAFT)聚合的双重引发剂。2-甲基和2-乙基-2-恶唑啉,用于经由CROP痘块,和丙烯酸甲酯,甲基丙烯酸甲酯,进行聚合Ñ,Ñ二甲基丙烯酰胺,Ñ,Ñ -diethylacrylamide,Ñ通过RAFT聚合,将-异丙基丙烯酰胺和4-丙烯酰基吗啉聚合为另一个嵌段。CROP和RAFT聚合以受控方式独立进行。
