MATRIX COPOLYMER, GRAFT COPOLYMER, AND THERMOPLASTIC RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2019/221448

Kind Code:

A1

Abstract:

The present invention relates to: a matrix copolymer comprising a cellulose nanocrystal derivative, an alkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit, and a vinyl cyanide-based unit; a graft copolymer comprising a cellulose nanocrystal derivative, a conjugated diene polymer, an alkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit, and a vinyl cyanide-based unit; and a thermoplastic resin composition comprising at least one of the copolymers. According to the present invention, provided can be a thermoplastic resin composition having improved processability, impact strength, tensile strength, and chemical resistance while maintaining transparency.
