The present invention is a matrix copolymer that is a copolymer of a first monomer mixture including a cellulose fiber, an alkyl (meth) acrylate monomer, an aromatic vinyl monomer, and a vinyl cyanide monomer; And In a thermoplastic resin composition comprising a graft copolymer obtained by graft copolymerization of a second monomer mixture including a cellulose fiber, an alkyl (meth)acrylate monomer, an aromatic vinyl monomer, and a vinyl cyanide monomer in a diene rubber polymer. As regards, the thermoplastic resin composition of the present invention is excellent in transparency, chemical resistance, thermal stability and mechanical properties by including cellulose fibers in the matrix copolymer and the graft copolymer. |
