| 摘 要： | 采用球形Z-N催化剂,使用乙烯、丙烯和1-丁烯作为共聚单体,分步聚合催化合成了三元多相共聚聚丙烯。这种乙丙丁三元共聚物中长乙烯基结晶链段含量少,橡胶相含量高,乙丙丁三元共聚合金中的橡胶相比其它二元共聚合金中橡胶相的相对分子质量分布窄。

| Abstract: | The preparation of polypropylene alloy by 2-stage heterophase catalytic copolymerization of ethylene, propylene and 1-butene on spheric Ziegler-Natta catalyst had been studied.The obtained polypropylene-ethylene-butene copolymer alloy possessed unique nature with low content of long ethyl sequence copolymer and high content of rubber.Especially rela2 mol?cular mass distribution of latter was more narrow than those of polypropylene-ethylene and polypropylene-butene rubber. |

| Keywords: | polypropylene polypropylene-ethylene-butene alloy relative molecular mass distribution rubber phase |
