Title:

PROCESS FOR PRODUCING INJECTION-MOLDED OBJECT

Document Type and Number:

WIPO Patent Application WO/2007/043190

Kind Code:

A1

Abstract:

A process for producing an injection-molded object characterized by injection-molding a mixture comprising a thermoplastic resin and a polyolefin wax at a molding temperature lower by at least 5°C than the molding temperature for the mixture which does not contain the polyolefin wax. In the injection molding of a thermoplastic resin by the process for producing an injection-molded object, resin scorching is prevented and cooling time after injection can be shortened.
