摘要
本文研究了以过氧化苯甲酰(BPO)为引发剂,甲基丙烯酸丁酯(BMA)既作溶剂又作为单体与苯乙烯-丁二烯嵌段共聚物(SBS)进行接枝共聚反应。用红外光谱、核磁共振谱及透射电镜表征了接枝共聚物(SBS-g-BMA)的组成及结构,讨论了时间、温度及SBS和BPO的用量对接枝的影响。
Butyl methacrylate (BMA) has been graft copolymerized onto styrene-butadiene-styrene block copolymer(SBS) by using butyl methacrylate as solvent simultaneously and benzoyl peroxide as initiator. The structure of the graft copolymer was determined by IR,NMR and TEM. Effects of polymerization temperature, time ,concentration of initiator and SBS on graft copolymerization were investigated.
