POLYCARBONATE RESIN HAVING AMINE RESISTANCE

Title:

POLYCARBONATE RESIN HAVING AMINE RESISTANCE

Document Type and Number:

WIPO Patent Application WO/2017/073508

Kind Code:

A1

Abstract:

A polycarbonate copolymer or copolymerized polycarbonate blend having excellent amine resistance, which is mainly composed of a constituent unit (A) represented by formula (1), a constituent unit (B) represented by formula (2) and a constituent unit (C) represented by formula (3), and wherein the ratio of the constituent unit (A) is 5-15% by mole, the ratio of the constituent unit (B) is 20-60% by mole and the ratio of the constituent unit (C) is 25-75% by mole, respectively in all constituent units. The polycarbonate copolymer or copolymerized polycarbonate blend has excellent scratch resistance, impact resistance, heat resistance and amine resistance. (In formula (1), each of R1 and R2 independently represents a hydrogen atom, a hydrocarbon group having 1-9 carbon atoms, which may contain an aromatic group, or a halogen atom.) (In formula (2), each of R3 and R4 independently represents an alkyl group having 1-6 carbon atoms or a halogen atom; and X represents a single bond, a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkylidene group, a sulfur atom or an oxygen atom.) (In formula (3), W represents a single bond, a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkylidene group, a sulfur atom or an oxygen atom.)
