PURPOSE:To obtain a molding, having a hinge part and excellent hinge characteristics and containing a polybutylene terephthalate-based copolymer excellent in productivity as a molding having the hinge part for various thermal apparatuses, automotive parts, electrical and electronic parts, etc. CONSTITUTION:The objective molding having a hinge part comprises a polybutylene terephthalate-based copolymer composed of a copolymer obtained from a dicarboxylic acid component consisting essentially of terephthalic acid and its derivative and a diol component consisting essentially of 1,4-butanediol and a polyalkylene glycol having 500-20000 weight-average molecular weight. The polyalkylene glycol component is contained in an amount of 0.5-3.5wt.% based on the copolymer. |
