摘要

对“饥饿”反应器中甲基丙烯酸甲酯（MMA）聚合行为进行详尽研究，建立了聚合动力学模型，模型中考虑了由于初级自由基与单体反应生成单体自由基时所消耗的单体量；考虑了PMMA的高温解聚作用；考虑了体系中的凝胶效应，并将链终止速率常数与凝胶效应联系起来，反映在模型中．通过实验，优化回归求取了模型参数．

Abstract

The kinetics of methylmethacrylate radical polymerization in a continuous phase semi-batch polymerization reactor is studied.In the reactor

monomer and initiator are fed at a constant

small rate into a fixed amount of solvent.This type of reactor is useful in the production of a low molecular weight polymer which can be used to make coating and adhesive formulations.The kinetics model incorporates the rate of monomer consumption due to the reaction of Primary radicals with monomer

the rate of PMMA depolymerization at high temperature and the termination rate constant dependent on the gel effect.The model constants are regressed with the help of experimental data.
