Abstract: A process for polymerizing propylene in the presence of a polymerization catalyst by polymerizing propylene with a comonomer selected from the group of ethylene and C4-C10 alpha-olefins in two polymerization stages where the comonomer is present in at least one of the polymerization stages. The first polymerization stage is conducted in a loop reactor and the second polymerization stage in a gas phase reactor. The polymer produced in first polymerization stage has a higher melt flow rate and a lower content of comonomer units than the final polymer mixture. The process can be operated with a high throughput and catalyst productivity. The polymers are useful for making films.

Abstract translation: 在聚合催化剂存在下，通过在共聚单体存在于至少一个聚合阶段的两个聚合阶段中将丙烯与选自乙烯和C 4 -C 10α-烯烃的共聚单体聚合来聚合丙烯的方法。 第一聚合阶段在环流反应器中进行，第二聚合阶段在气相反应器中进行。 在第一聚合阶段中生产的聚合物具有比最终聚合物混合物更高的熔体流动速率和更低的共聚单体单元含量。 该方法可以以高产量和催化剂生产率运行。 聚合物可用于制备薄膜。
