Manufacture of surface-metallized molded article of polybutylene terephthalate resin

Abstract

Abstract PURPOSE:To improve the mechanical properties, especially the shock resistance and the thermal cycle properties by adding a specified polyester to a blend of polybutylene terephthalate with TiO2 of a specified particle size when a molded article of the blend is plated after roughening the surface with an alkali soln. CONSTITUTION:To 100pts. polyester resin consisting of 97-50wt% polybutylene terephthalate (A) and 3-50wt% copolymerized polyester (B) contg. dicarboxylic acid is added 10-250pts. TiO2 of 1-6mum average particle size. A molded article of the thermoplastic polyester resin is plated after roughening the surface with an alkali soln. to obtain the titled molded article having superior bonding strength to a film formed by the plating, fine surface luster, superior mechanical properties and thermal cycle properties. The component B is a copolymer consisting of a component contg. about 3-50mol% aliphatic dicarboxylic acid and a diol component.
