- CORE-SHELL COPOLYMER METHOD FOR PREPARING THE SAME AND POLYCARBONATE BASED RESIN COMPOSITION COMPRISING THE CORE-SHELL COPOLYMER

摘要

The present invention relates to a core comprising a repeating unit derived from a diene-based rubber monomer and a repeating unit derived from an aromatic vinyl-based monomer; and a graft shell surrounding the core and containing a repeating unit derived from an alkyl (meth)acrylate monomer and a repeating unit derived from an aromatic (alkyl)methacrylate monomer, wherein the core has a refractive index of 1.53 to 1.54, and the refractive index of the shell is 1.55 to 1.56; The core has an average particle diameter of 100 to 150 nm, and the core-shell copolymer has an average particle diameter of 110 to 180 nm, and a method for preparing the same.
