Patent ID: 8133943

Claim:
A polylactic acid/polycarbonate resin composition comprising: (A) about 100 parts by weight of a mixed resin comprising (a1) 70 to about 90 wt % of a polycarbonate resin and (a2) about 10 to 30 wt % of a polylactic acid resin; (B) about 1 to about 50 parts by weight of a flame retardant based on about 100 parts by weight of the mixed resin; (C) about 1 to about 30 parts by weight of an acryl-based copolymer wherein the acryl-based copolymer is a copolymer comprising at least two monomers selected from linear alkyl (meth)acrylate monomers, branched alkyl (meth)acrylate monomers, cyclic alkyl (meth)acrylate monomers, or combinations thereof; or a copolymer prepared by grafting a reactive group onto a monomer selected from linear alkyl (meth)acrylate monomers, branched alkyl (meth)acrylate monomers, cyclic alkyl (meth)acrylate monomers, or combinations thereof based on about 100 parts by weight of the mixed resin; and (D) about 1 to about 20 parts by weight of an impact-reinforcing agent based on about 100 parts by weight of the mixed resin.
