METHOD FOR MANUFACTURING POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION AND METHOD FOR MANUFACTURING POLYBUTYLENE TEREPHTHALATE RESIN MOLDED ARTICLE

Document Type and Number:

WIPO Patent Application WO/2017/014239

Kind Code:

A1

Abstract:

Provided is a technique for reducing the release of VOCs, said VOCs including VOCs other than THF, from a polybutylene terephthalate resin molded article containing a polybutylene terephthalate resin. The present invention relates to: a method for manufacturing a polybutylene terephthalate resin composition that contains a polybutylene terephthalate resin produced by a direct esterification method and an alkali compound, said method comprising a step for melt-kneading a master batch containing a polyalkylene terephthalate resin and the alkali compound with the polybutylene terephthalate resin; and a method for manufacturing a polybutylene terephthalate resin molded article that contains a polybutylene terephthalate resin produced by a direct esterification method and an alkali compound, said method comprising a step for dry-blending the master batch with the polybutylene terephthalate resin and then molding the obtained blend.
