本体溶液法合成超高分子量聚苯乙烯

Synthesis of Ultra High Molecular Weight Polystyrene by Bulk Solution Polymerization

对２，３－二氰基－２，３－二苯基丁二酸二乙酯引发苯乙烯本体溶液聚合、合成超高分子量聚苯乙烯的宏观动力学进行了研究。结果表明，这种引发剂在苯乙烯中引发聚合性能温和，在一定条件下，随反应时间的增长，聚合产物的分子量不断增高，可形成超高分子量聚合物。

The synthesis of ultra high molecular weight polystyrene was carried out by bulk solution polymerization which was initiated with diethy1 2,3-dicyano-2,3-bisphenyl succinate in ethylbenzene.The results indicate that the initiator behaved mildly and that the molecular weight of the polystyrene product increased along with the reaction time.
