dc.description.abstract活性聚合以其无链转移、无链终止和引发速度远大于增长速率的特点,应用于合成单分散聚合物、预定序列结构的嵌段共聚物等.常用的活性聚合方法如阴离子聚合、阳离子聚合及基团转移聚合对反应条件要求苛刻,不能用于丙烯酸酯类极性单体和苯乙烯类非极性单体的嵌段共聚.与...
dc.description.abstractThe application of atom transFer radical polymerization For the synthesis of controlled block copolymer of styrene and butyl methacrylate was discribed in this paper.For instance, butylmethacrylate was First polymerized by using 1 PECl, CuCl and bipyridine in a molar ratio of l∶1∶2 at 120 ℃ For 2 h, the bulk polymerization proceeded to about 96% conversion.When styrene was subsequently added to the controlled polybutyl methacrylate synthesized as described above and polymerized at the same temperature For 5 h, the block copolymers of BMA and S with predicted molecular weight(1×10 4~4×10 4) and narrower molecular weight distribution(1 1~1 5) were obtained.When the First monomer was changed to styrene, it needed more time to get high conversion.
