氯化钕配合物催化4-乙烯吡啶聚合反应动力学研究

Studies on the Kinetics of 4-Vinylpyridine Polymerization with Complex of Neodymium Chloride Catalyst System

研究了氯化钕配合物催化４－乙烯吡啶聚合反应动力学，通过考察反应时间、催化剂浓度和温度对聚合反应的影响，建立了该体系动力学方程，并求取出反应级数为１，表观活化能约为４８．８６ｋＪ／ｍｏｌ。

The paper reports the kinetics study of 4-vinylpyridine polymerization with P(St-co-AM)NdCl 3-Al(i-Bu) 3 and NdCl 3·4DMSO-Al(i-Bu) 3 as catalyst.Effects of polymerization temperature and catalyst concentration on rate of polymerization were investigated.The kinetics equation can be expressed as follows -ddt=k P 1.0 1.0 0 The apparent activation energy is 48.86 kJ/mol.
