摘要
用乳液接枝法合成了氯丁橡胶（ＣＲ）－甲基丙烯酸甲酯（ＭＭＡ）接枝共聚物，并用喷雾干燥法制得了粉末状干胶。研究了氯丁二烯转化率、相对分子质量调节剂用量、残留氯丁二烯含量、接枝聚合温度、ＭＭＡ用量等对接枝共聚物溶解性和接枝率的影响。
The graft copolymer of chloroprene rubber(CR)/ methyl methacylate(MMA) was prepared by emulsion graft polymerization,and powdered CR/MMA dry rubber was obtained by spray-drying.The effects of chloroprene conversion,relative molecular mass adjuster concentration,residual chloroprene content,graft polymerization temperature,and CR/MMA ratio on graft percent and the copolymer properties were investigated.
