To provide a compatibilizing agent which improves the compatibility of an aliphatic polyester resin and a general-purpose polyolefin resin, in a small amount of the addition, and can impart, to a thermoplastic resin composition composed thereof, good moldability, sufficient mechanical properties, impact resistance, heat resistance and hydrolysis resistance.
An oxazoline-based aliphatic polymer being a homopolymer of an alkenyloxazoline or a radical copolymer of an alkenyloxazoline and a (meth)acrylamide-based monomer and/or a (meth)acrylate ester, or an oxazoline-modified polyolefin obtained by using the oxazoline-based aliphatic polymer is used as a compatibilizing agent. The thermoplastic resin composition is obtained by dry-blending and melt-kneading an aliphatic polyester resin, a polyolefin resin and the compatibilizing agent.
