摘　　要：以过氧化二苯甲酰(BPO)为引发剂,水为分散相,聚乙烯醇(PVA)为分散剂,用既可作溶剂又可作共聚单体的甲基丙烯酸甲酯(MMA)与SBS在开放体系下进行悬浮接枝共聚反应。并用红外光谱对接枝物进行了表征,同时研究了合成条件对接枝共聚物剥离强度的影响。Using BPO as intiator, water as medium, PVA as dispersing agent, MMA as grafting monomer and solvent, SBS-g-MMA was performed in open suspension copolymerization system. The grafted copolymer was characterized by IR spectrosocopy. The effect of polymerization condition on peeling strength of copolymer was also studied.
