Title:
POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION AND METAL COMPOSITE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2017/115757
Kind Code:
A1
Abstract:
A polybutylene terephthalate resin composition which contains (A) a polybutylene terephthalate resin, (B) a polyethylene terephthalate resin and (C) an epoxy group-containing olefin copolymer that contains (c-1) a constituent unit derived from an α-olefin and (c-2) a constituent unit derived from a glycidyl ester of an á, β-unsaturated acid. A molded article of this polybutylene terephthalate resin composition, which is molded at a molding temperature of 260°C under a holding pressure of 80 MPa with a mold temperature of 80°C in accordance with ISO 3167 (Type A test piece), has a surface roughness of 0.50 μm or less. The content of the epoxy groups in the epoxy group-containing olefin copolymer (C) is from 0.01% by mass to 0.35% by mass (inclusive) relative to the total mass of the polybutylene terephthalate resin composition; and the content of (meth)acrylate ester structures is 1.5% by mass or less relative to the total mass of the polybutylene terephthalate resin composition.
