Polyester-Series Resin Composition and Molded Article |
摘要 |
A polyester-series resin composition comprises (A) a polyester block copolymer and (C) a polycarbodiimide compound, and if necessary (B) a polyepoxy compound. The copolymer (A) is obtainable by reaction of (a1) a crystalline aromatic polyester and (a2) a lactone, and if necessary (a3) at least one compound selected from the group consisting of a polycarboxylic acid or an ester-formable derivative thereof and a polyol or an ester-formable derivative thereof in the presence of a phosphorous ester. Such a resin composition is particularly excellent in recycling efficiency and is useful for blow molding. The resin composition has a high hydrolysis resistance and an excellent heat resistance (particularly thermal cycling resistance).
