THERMOPLASTIC POLYURETHANE ADDITIVES FOR CHAIN EXTENSION AND REACTIVE EXTRUSION

摘要

The invention relates to a method for marking a polymer composition by melt mixing a composition composed of a polymer having at least one isocyanate reactive group and a thermoplastic polyurethane, wherein the thermoplastic polyurethane is less than 5 % by weight of the composition, wherein the polymer is not a polyamide. Preferably the polymer is a polyester, a liquid crystalline polymer or a polycarbonate. The invention further relates to a polymer composition produced by the present invention. The invention further relates to an article composed of the polymer composition produced by the present invention.
