Abstract

A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, and a compatibilizing agent. The compatibilizing agent comprises (i) an acyclic carbon-carbon double bond having a first carbon atom and a second carbon atom, (ii) an electron withdrawing group directly bonded to the first carbon atom in the acyclic carbon-carbon double bond, and (iii) a second carbon-carbon multiple bond in conjugation with the acyclic carbon-carbon double bond, wherein the second carbon-carbon multiple bond is linked to the acyclic carbon-carbon double bond through the second carbon atom.

First claim

What is claimed is:

1. A heterophasic polymer composition comprising:
(a) a propylene polymer phase comprising propylene polymers selected from the group consisting of polypropylene homopolymers and copolymers of propylene and up to 50 wt. % of one or more comonomers selected from the group consisting of ethylene and C 4 -C 10 α-olefin monomers;
(b) an ethylene polymer phase comprising ethylene polymers selected from the group consisting of ethylene homopolymers and copolymers of ethylene and one or more C 3 -C 10 α-olefin monomers; and
(c) a compatibilizing agent, the compatibilizing agent comprising (i) an acyclic carbon-carbon double bond having a first carbon atom and a second carbon atom, (ii) an electron withdrawing group directly bonded to the first carbon atom in the acyclic carbon-carbon double bond, and (iii) a second carbon-carbon multiple bond in conjugation with the acyclic carbon-carbon double bond, wherein the second carbon-carbon multiple bond is linked to the acyclic carbon-carbon double bond through the second carbon atom.

2. The heterophasic polymer composition of claim 1 , wherein the second carbon-carbon multiple bond is a carbon-carbon double bond.
