Modified Polyalkylene Terephthalate Resin for Improving Adhesion, Modified Polyalkylene Terephthalate Resin Composition for Improving Adhesion, Resin Molded Article, and Bonded Article

摘要

To provide a technique of improving adhesion of a resin molded article including a polyalkylene terephthalate resin to a silicon adhesive. A polyalkylene terephthalate resin is used in which an aromatic dicarboxylic acid excluding terephthalic acid, and/or an ester compound thereof is subjected to copolymerization as a modified component, and the content of the modified component relative to the total dicarboxylic acid component is at least 13 mol % and no more than 35 mol %. It is preferable if the modified polyalkylene terephthalate resin is a modified polybutylene terephthalate resin, and the aromatic dicarboxylic acid and/or an ester compound thereof is isophthalic acid and/or an ester compound thereof.
