摘　　要：采用悬浮聚合方法合成了苯乙烯 -甲基丙烯酸缩水甘油酯 (GMA)共聚物 (SG) ,讨论了各种实验条件对聚合反应的影响。SG共聚物能够有效地与尼龙 6分子链端的胺基、羧基和聚苯醚分子链端的羟基发生反应 ,生成接枝共聚物。将其用于尼龙 6/聚苯醚共混体系 ,发现尼龙 6(PA6) /聚苯醚 (PPO) /SG三元合金体系与组成相同的PA6/PPO二元合金体系相比 ,材料的拉伸强度和断裂伸长均得到提高。这种共聚物可以作为适用于尼龙Styrene-glycidyl methacrylate copolymer (GMA) was synthesized by suspension polymerization,and the effect of various experimental factors on the polymerization were also studied. The SG copolymer can react efficiently with the amide and carboxyl group of PA6 as well as the hydroxyl group of PPO in blending process, resulting into graft copolymer. With the existance of SG copolymer, both the tensile strength and the elongation at break of the PA6/PPO immiscible blend is improved apparently, so that this copolymer could be used as reactive solubilizer in PA/PPO blends.
