发明名称 Process for producing weather-resistant polycarbonate with triazine-imide chain terminator
摘要 A process for producing a weather-resistant polycarbonate resin by solution polymerization, of at least one dihydric phenol and phosgene in which a compound represented by formula (I): <IMAGE> (I) wherein R1, R2, and R3, each represents a hydrogen atom, a halogen atom, a nitro group, an alkyl group having from 1 to 20 carbon atoms, an alkoxy group having from 1 to 20 carbon atoms, or an aryl group having from 6 to 20 carbon atoms; m represents 1 or 2; and n represents an integer of from 1 to 10, is used as a terminator. The polycarbonate resin produced exhibits high weather resistance without suffering from volatilization.
