Claims20
A copolycarbonate resin, wherein the copolycarbonate resin is prepared by polymerizing a bisphenol based monomer, a comonomer represented by Formula 1 below, and a carbonate precursor, and an amount of the comonomer is 0.1 to 19% by weight based on a total weight of the bisphenol based monomer and the comonomer:
- R1 and R2 are each independently C1 to C10 alkylene, and n is an integer of 1 to 50.
A method of preparing a copolycarbonate resin, the method comprising a step of interfacially polymerizing a bisphenol based monomer, a comonomer represented by Formula 1 below, and a carbonate precursor:
- wherein R1 and R2 are each independently C1 to C10 alkylene, and n is an integer of 1 to 50.
A copolycarbonate resin composition, comprising 100 parts by weight of the copolycarbonate resin according to claim 1, 0.005 to 0.5 parts by weight of a diphosphite compound, 0.001 to 0.5 parts by weight of alicyclic epoxy compound, and 0.01 to 1 parts by weight of modified silicone.
