It was concluded from the experiment that the content of the isotactic polymer was the lest, the syndiotactic polymer was the most and the atactic polymer was between them. 由实验得到以下主要结论:PA-18降凝剂结构中全同立构聚合物含量最少,间同立构聚合物含量最多,无规立构聚合物含量介于两者之间。
Syndiotactic polystyrene ( sPS) produced with metallocene catalyst is a novel crystalline polymer that possesses excellent electronic/ electric properties and good abilities to resist heat and chemicals. 用茂金属催化剂制得间规聚苯乙烯(sPS)是一类新型结晶聚合物,具有优良的耐热性、耐化学性和电气性能。
