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.
