CHLORINE-RESISTANT RESIN COMPOSITION, CHLORINE-RESISTANT THERMOPLASTIC MOLDED ARTICLE, AND BELT

摘要

Provided are: a thermoplastic resin composition which exhibits chlorine resistance and has excellent appearance; a chlorine-resistant thermoplastic molded article; and a belt. The thermoplastic resin composition comprises a polymeric diol comprising at least one of a polycaprolactone diol, a polyether diol and a polycarbonate diol each having a number average molecular weight of 750 to 3000, a chain extending agent comprising a diol having a number average molecular weight of 60 to 300 and an organic diisocyanate. In the thermoplastic resin composition, a novel additive is used in combination, whereby the amounts of a coloring agent and a conventional chlorine-resistant agent can be controlled to small levels.
