摘要
本文对“饥饿”反应器中ＡＩＢＮ引发苯乙烯聚合行为进行了详细的研究，建立了相应的聚合动力学模型。在模型中，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，并将链终止速率常数与聚合物的累积数均链长进行校正。
Kinetics of STY free radical polymerization in a continuous phase semi-batch polymerization reactor was studied. In the reactor. monomer and initiator were fed at a constant small rate into a fixed amount of solvent. This type of reactor is useful in the production of low molecular weight polymer which can be used to make coating and adhesive formulations. The kinetics model incorporated the rate of monomer consumption due to the reaction of primary radicals with monomer and the chain length dependence of the termination rate constant on the cumulative degree of polymerization.The model constants were regressed with the help of experimental data.
