Abstract

Monophasic propylene copolymer with high stiffness and impact resistance.

Description

technical field [0001] The present invention relates to a novel propylene copolymer, a process for its preparation and articles made therefrom. Background technique [0002] Propylene copolymers are well known and are often used in the packaging field. Packaging materials combining high transparency and high impact strength are needed in this technical field. High fluidity of commonly used polymers is also expected. However, since the improvement of one property comes at the expense of others, using one polymer to meet all requirements is a tall order. [0003] EP2281851 describes a bimodal propylene copolymer. One fraction of the copolymer is a propylene homopolymer. The impact strength values ​​are rather low. [0004] EP0860457 discloses a multiphase system. Even with the elastomer phase, the impact performance is not very high. [0005] EP0339804 relates to a modified polypropylene. Again, shock performance isn't great. [0006] It is therefore necessary to prov...
