摘　　要：气液悬浮体系中单体同接枝骨架在分散液滴内进行自由基接枝聚合时,由于气体热容小、导热差、聚合热积集促成分散气体先膨胀后逸出,使聚合反应动力学特征出现较大差异.研究差异的表征方法及对产物的影响,探讨延缓气体逸出的因素及利用逸出气体带走体系内小分子的最佳条件为建立以气体为分散介质,以单体、接枝骨架,引发剂等聚合组分液滴为分散相,在分散相内引发聚合的机理模型,提供基础研究数据.Since gas is possessed of a small heat capacity nd a bad heat corrective property, the gas phase will be swell nd escape successively when the polymerisation heat accumulates uninterruptedly in the course of graft polymerisation tking place in a small isolated droplets which suspended on a gas continuous phase. This led to a large difference between the swelled and escaped on the kinetic characters of the process. The character of the difference, the inference of the difference on the products, the effects of gas controlling escape and using escaped gas to bring the small molecule are discussed.
