丙烯腈-丙烯酸甲酯-衣康酸在氯化锌溶液中的聚合反应

STUDY ON AN MA IA POLYMERIZATION IN ZnCl2 SOLUTION

以一种有机过氧化物（ＯＰＯ）和有机还原剂（ＯＲＡ）组成的新引发体系，在ＺｎＣｌ２溶液中研究了ＡＮ－ＭＡ－ＩＡ的溶液共聚合反应。结果表明，初始聚合反应速度与两种引发剂各自浓度的１／２次方成正比，与单体浓度［Ｍ］的３／２次方成正比，并求得聚合反应表观活化能为４９．９１ｋＪ／ｍｏｌ。聚合体浆液稳定，可直接纺丝。

N MA IA solution polymerization in ZnCl2 solution was investigated with a new initiator system composed by an organic peroxide and an organic reducing agent.The experimental results indicated that the velocity of initial polymerization was in direct proportion to 1/2 power of the catalyst concentration and to 3/2 power of the monomer concentration.The apparent activation energy of polymerization was 49.91 kJ/mol from calculation.The polymer solution was stable and could be directly spined.
