采用封闭体系,通过甲基丙烯酸甲酯的原子转移自由基聚合生
成B段,并以此为大分子引发剂引发甲基丙烯酸缩水甘油酯(GMA)聚
合,得到AB嵌段聚合物PMMAbPGMA.分别利用对硝基苯甲酸与二
丁基胺对该聚合物中的环氧基团进行基团改性,制备了两亲性的AB
嵌段聚合物.采用GPC、FTIR以及化学分析等方法,对所制备的AB
嵌段聚合物进行了结构表征.
An AB bolck copolymer PMMAbPGMA was
prepared by the addition of glycidyl methacrylate(GMA)
to macromolecular innitiator polymethylmethacrylate
(PMMA)which was synthesized first via atom transfer
radical polymerization in a closed system. The epoxy
group, contained in the AB block copolymer (PMMAb
PGMA)was then modified by pnitrobenzzoic acid and
dibutylamine and the amphiphilic AB block copolymers was
obtained. The structure of the block copolymers was
characterized with GPC, FTIR and chemical analysis.
