Title:
ACRYLIC THERMOPLASTIC RESIN COMPOSITION, MOLDED ARTICLE, FILM AND METHOD FOR PRODUCING SAME, AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2017/188290
Kind Code:
A1
Abstract:
The present invention provides a thermoplastic resin composition having excellent transparency, flexibility and moldability. The acrylic thermoplastic resin composition according to the present invention comprises acrylic multilayer-structured polymer particles (A) and an acrylic block copolymer (B). The component (A) has a rubber component layer (I), which is composed of a copolymer comprising 50 to 99.99% by mass of an acrylic acid ester monomer unit, 49.99 to 0% by mass of another monofunctional monomer unit and 0.01 to 10% by mass of a polyfunctional monomer unit, in the inside thereof, and also has a thermoplastic resin component layer (II), which is composed of a copolymer comprising 40 to 100% by mass of a methacrylic acid ester monomer unit and 60 to 0% by mass of another monomer unit and having a Mn of 30,000 or less, as the outermost layer, wherein the (layer (I))/(layer (II)) ratio is 30/70 to 90/10 by mass, and the average particle diameter is 150 nm or less. The component (B) has a Mw of 32,000 to 300,000. The (A)/(B) ratio is 1/99 to 99/1 by mass.
