摘要

本文研究了一种新的烯烃聚合活性中心浓度测定方法

即CO阻聚法

并在此基础上测定了络合型催化剂丙烯气相聚合的活性中心浓度、链增长速度常数及活化能;证实了该方法用于丙烯气相聚合的可靠性及其主要影响因素是CO对活性中心的“多次阻聚”

同时从实验上证明丙烯聚合速度衰减是由于活性中心浓度降低。

Abstract

The inhibition method using CO to determine the active center concentration C in gas-phase polymerization of propene were studied. The method is found to be also reliable when used in gas-phase polymerization and mainly affected by the "repeating inhibition" of CO to the active centers. It is proved experimentally that polymerization rate decay coincides with the decrease of C.
