摘要

聚合反应工程分析是《聚合反应工程基础》课程的核心内容，其中聚合反应速度的工程分析是学习聚合度及聚合度分布、聚合反应机理确定、聚合过程控制的前提，正确理解及领会聚合速度工程分析的基本概念及意义，掌握不同条件下的聚合反应特点，有助于学生对该类推导过程的掌握及具体聚合机理和过程的分析。本文针对教材中缺乏聚合反应速度相关详细分析这一问题，以连锁聚合为例，探讨了间歇聚合与连续操作方式下，拟稳态假设成立及不成立时，活性链浓度与转化率的关系、转化率与聚合反应时间之间的关系。

Abstract

In this paper

the relationships between active chain concentration ([

·]) and conversion (

)

conversion and polymerization time (

) with or without the quasi-stable state hypothesis were discussed. Under the quasi-stable state

curve

not [

·]~

curve

is influenced by the operation mode. With the polymerization mechanism of initiator trigger and coupling or disproportionation termination

higher conversion could be gained in batch reactor than that in continuous stirred tank reactor under the same polymerization time. Without the quasi-stable state hypothesis

both [

·]~

curve and

curve are influenced by the operation mode. With the polymerization mechanism of initiator trigger and no termination

higher conversion could be gained in continuous stirred tank reactor than that in batch reactor under the same polymerization time. We hope that the results could contribute to the teaching of lectures and studying of undergraduates.
