<p>PURPOSE: A thermoplastic resin containing a cross-linked phase is provided which can form a granular easily and gives the good appearance of molded pipe obtained by extruding it. CONSTITUTION: A thermoplastic resin composition comprising a thermoplastic polymer containing a cross-linked phase generated from the reaction of (A)a product containing unsaturated epoxide, (B)a product containing carboxylic acid anhydride and (C)a product of alpha, omega-aminocarboxylic acid or unsaturated carboxylic acid. Preferably the product(A) is a copolymer of ethylene, C2-10 alkyl(meth)acrylate and unsaturated epoxide and has, for example, a melt flow index of 0.1-50(g/10 min, 2.16 kg, 190°C). Preferably the product(B) is a copolymer of ethylene and unsaturated carboxylic acid anhydride, or polyolefin grafted with unsaturated carboxylic acid anhydride and has, for example, a melt flow index of 0.1-50(g/10 min, 2.16 kg, 190°C). Preferably the product(C) is a copolymer of ethylene and (meth)acrylic acid has, for example, a melt flow index of 0.1-50(g/10 min, 2.16 kg, 190°C).</p> |
