    Effects of Methyl Methacrylate and Divinylbenzene on the Copolymerization of Styrene

      摘要
    • 摘要: 以甲基丙烯酸甲酯(MMA)、苯乙烯(St)和二乙烯苯(DVB)三元共聚体系为研究对象,采用气相色谱法研究了体系中MMA和DVB浓度对聚苯乙烯型树脂交联的影响。结果表明:MMA加速St和DVB的聚合速率,其中对St的加速作用又明显大于对DVB的。随MMA含量的增加,聚苯乙烯型树脂交联不均匀的情况得以明显改善,而增加体系中DVB的含量,DVB与St、MMA反应速率的差异变大,树脂交联不均匀的情况变严重。
