A method for making a polymer composition comprises the steps of providing a heterophasic thermoplastic polymer composition, providing a compatibilizing agent, providing a peroxide compound, and mixing and melting the heterophasic thermoplastic polymer composition, compatibilizing agent, and peroxide compound. The compatibilizing agent comprises an ester compound formally derived from a polyol comprising three or more hydroxy groups and an aliphatic carboxylic acid comprising one or more carbon-carbon double bonds. A modified polymer composition comprises a heterophasic thermoplastic polymer composition and a compatibilizing agent. The modified polymer composition has an ethylene discontinuous phase present in the form of discrete particles in a propylene continuous phase. The discrete particles of the ethylene discontinuous phase are present in the modified polymer composition in a concentration of 2.1 or more particles per cubic micron.
