Synthesis of poly(ethyl acrylate)-g-poly(methyl methacrylate) via atom transfer radical polymerization with poly(ethyl acrylate-co-ethyl 2-bromoacrylate) as the macroinitiator

丙烯酸乙酯与 2 溴丙烯酸乙酯乳液共聚合制备了聚 (丙烯酸乙酯 co 2 溴丙烯酸乙酯 )无规共聚物 ,用该共聚物作为原子转移自由基聚合的大分子引发剂 ,进行了甲基丙烯酸甲酯的接枝聚合 ,制备了聚丙烯酸乙酯 g 聚甲基丙烯酸甲酯接枝共聚物。接枝共聚物的分子量随单体转化率的上升而线性增加。

Poly(ethyl acrylate)-g-poly(methyl methacrylate) was synthesized via atom transfer radical polymerization with poly(ethyl acrylate-co-ethyl 2-bromoacrylate) as the macroinitiator, which was obtained by emulsion copolymerization of ethyl acrylate and ethyl 2-bromoacrylate. The molecular weights of the graft copolymers increased linearly with the conversion of methyl methacrylate, showing that the grafting copolymerization was a living process.
