WIPO Patent Application WO/2019/124787
Kind Code:
A1
Abstract:
A polycarbonate copolymer of the present invention is a polymer of: a polycarbonate resin having a weight average molecular weight of about ≥5,000 and about ≤20,000 g/mol; and at least one of an aliphatic polyether resin having a weight average molecular weight of about ≥1,000 and about ≤ 10,000 g/mol and an aliphatic polyester resin having a weight average molecular weight of about ≥3,000 to about ≤10,000 g/mol, wherein the content of the polycarbonate resin in 100 wt% of the polymer is about ≥70 and about ≤99 wt%, and the content of at least one of the aliphatic polyether resin and the aliphatic polyester resin is about ≥1 to about ≤30 wt%. The polycarbonate copolymer, the thermoplastic resin composition comprising the same, and the molded product manufactured therefrom are excellent in moldability, thermal stability, tensile elongation, and the like.
