本文研究了若干参数对聚乙烯醇与苯乙烯輻射接枝共聚反应的影响,并对接枝产品的性能作了初步鉴定。在体系里加入适量的水接枝卽甚易发生,此后接枝率先随着聚合物膜片的水合量而急剧增加,然后趋于平坦;而均聚反应速度增加較慢,且在水含量較低时就不再上升。研究了剂量 In this paper, the effects of several parameters on graft copolymerization of polyvinyl alcohol with styrene were studied. The properties of the grafted products were preliminarily identified. In the system to join the right amount of water grafting 卽 very easy to occur, then the first graft with the polymer membrane hydration and the sharp increase, and then tends to be flat; and the homopolymerization reaction increases slowly, and in the water content of Low no longer rise. The dose was studied
