Title:
THERMOPLASTIC RESIN COMPOSITION AND MOLDING THEREOF
Document Type and Number:
Japanese Patent JP2019137751
Kind Code:
A
Abstract:
To provide a thermoplastic resin composition that can provide a thermoplastic resin molding having excellent impact resistance, low-temperature impact resistance, color development, glossiness, mold appearance, and weather resistance, with the mold appearance having low molding speed dependence.SOLUTION: A thermoplastic composition contains the following components (B), (D) and a thermoplastic resin (E). Component (B): a graft copolymer in which a rubbery polymer (A) containing a (meth) acrylate, a crosslinker, and a hydrophobic material having a hydrocarbon group selected from an alkyl group, an alkenyl group and a cycloalkyl group having 12 or more carbon atoms, and with an acetone swelling degree of 500-1500% and a volume average particle diameter of 200-800 nm, is graft polymerized with at least one of aromatic vinyl, (meth) acrylate and vinyl cyanide. Component (D): a graft copolymer in which a rubbery polymer (C) with a volume average particle diameter of 50-190 nm is graft polymerized with at least one of aromatic vinyl, (meth) acrylate and vinyl cyanide.SELECTED DRAWING: None
