Title:
THERMOPLASTIC ACRYLIC RESIN AND METHOD FOR PRODUCING SAME, AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/187404
Kind Code:
A1
Abstract:
In at least one embodiment, the present invention relates to a thermoplastic acrylic resin which is a graft copolymer in which a stem polymer is an acrylic resin containing acrylonitrile and another ethylenically unsaturated monomer and a branch polymer is a polymer comprising an ethylenically unsaturated monomer, wherein acrylonitrile is contained in an amount of 35 to 84.5% by mass inclusive, the other ethylenically unsaturated monomer is contained in an amount of 15 to 64.5% by mass inclusive, and the polymer comprising an ethylenically unsaturated monomer is contained in an amount of 0.5 to 40% by mass inclusive. Provided are: a thermoplastic acrylic resin which is improved in melt processability without being deteriorated in heat resistance; a method for producing the thermoplastic acrylic resin; a thermoplastic acrylic resin composition; a molded article; an acrylic fiber; and a method for producing the acrylic fiber.
