Provided is a resin composition which can be molded into a product with excellent transparency, as a recycled composition of a multilayer structure using a polyolefin resin and an ethylene-vinyl alcohol copolymer. The resin composition comprises a polyolefin resin (A), an ethylene-vinyl alcohol copolymer (B), and an amine-modified resin (C), wherein the content of the amine-modified resin (C) is 0.1 to 20 parts by mass per 100 parts by mass of the polyolefin resin (A).

A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, and a compatibilizing agent. The compatibilizing agent comprises (i) at least one tertiary carbon-hydrogen bond having a bond-dissociation energy of about 380 kJ/mol or less and (ii) at least one acyclic carbon-carbon double bond. A method of making a heterophasic polyolefin polymer composition comprises the steps of (a) providing a propylene polymer phase and an ethylene polymer phase, (b) providing a compatibilizing agent, and (c) mixing the propylene polymer phase, the ethylene polymer phase and the compatibilizing agent, in the presence of free carbon radicals. The compatibilizing agent reacts with propylene polymers and ethylene polymers thereby bonding propylene polymers to ethylene polymers.
