探讨了聚氧化丙烯端基的不饱和性、官能度及反应性之间的关系前言聚氨酷材料为了得到满意的机械性能,要求合成一定分子量及官能度的聚氧化丙烯。国内对聚氧化丙烯的官能度测定和研究工作做得不多,并且往往把参与反应的起始官能度澡吐略地作为聚合产物的官能度。 The relationship between the unsaturation, functionality and reactivity of polyoxypropylene end groups is discussed. Polyurethane Materials In order to obtain satisfactory mechanical properties, it is desirable to synthesize polyoxypropylene of a certain molecular weight and functionality. The domestic polypropylene polymerization and the determination of the work done very little, and often take the reaction of the initial functionality of the bath spit as a polymerization product functionality.
