Polybutylene terephthalate resin composition, molded article composed of polybutylene terephthalate resin composition, inhibitor for increasing viscosity of polybutylene terephthalate resin composition, hydrolysis inhibitor for molded article composed of polybutylene terephthalate resin composition

摘要

PROBLEM TO BE SOLVED: To add water to a polybutylene terephthalate resin composition, a molded product, a polybutylene terephthalate resin composition viscosity increase inhibitor, and a polybutylene terephthalate resin composition, which are excellent in improving dimensional accuracy and hydrolysis resistance. An object of the present invention is to provide a decomposition inhibitor. SOLUTION: The polybutylene terephthalate resin (A) having a carboxylic acid terminal group of 35 meq / kg or less is 100 parts by mass, and the epoxy resin (B) is 0.5 parts by mass or more and 10 parts by mass or less, and a quaternary ammonium salt. A polybutylene terephthalate resin composition containing (C) and a dimensional accuracy improving agent (D), a molded product comprising the above polybutylene terephthalate resin composition, and a polybutylene terephthalate resin composition containing a quaternary ammonium salt. The above-mentioned problems are solved by the hydrolysis inhibitor of a molded product made of a polybutylene terephthalate resin composition containing a viscosity increase inhibitor and a quaternary ammonium salt.
