Abstract: The present invention relates to a process for producing a propylene terpolymer comprising comonomer units derived from ethylene and from one alpha-olefin selected from the group of C 4 -C 8 alpha-olefins and being characterized by a total content of comonomer units not less than 8 % wt and a value of the ratio of ethylene to the C 4 -C 8 alpha-olefins ranging from 0.1 to 0.8, said process being carried out in a gas-phase reactor comprising two interconnected polymerization zones. The present invention further relates to the propylene terpolymer obtained by said process particularly suitable to be used as films such as cast films, bi- or mono-oriented films and heat-sealable films having good optical properties and excellent sealing properties combined with good shrinkage properties and softness.

Abstract translation: 本发明涉及一种制备丙烯三元共聚物的方法，其包括衍生自乙烯和选自C4-C8α-烯烃的一种α-烯烃的共聚单体单元，其特征在于共聚单体单元的总含量不低于8％ wt，乙烯与C 4 -C 8α-烯烃的比例为0.1至0.8，所述方法在包含两个互连聚合区的气相反应器中进行。 本发明还涉及通过所述方法获得的丙烯三元共聚物，其特别适合用作膜，例如流延膜，双或单取向膜和具有良好光学性能和优异的密封性能以及良好收缩性能的可热封膜 和柔软度。
