Title:
RESIN COMPOSITION CONTAINING POLYMER PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/155677
Kind Code:
A1
Abstract:
A resin composition containing a thermoplastic resin and mixed particles which include polymer particles I and polymer particles II in a mass ratio (polymer particles I/polymer particles II) of 55/45 to 75/25, wherein: the polymer particles I exhibit a weight average molecular weight of the soluble acetone content thereof of 70,000-100,000, and a volume average particle diameter as measured by the light-scattering method of 150-300 nm, and have a three-layer structure in which the innermost layer comprises a rigid polymer c, 80-100 mass% of which is a methacrylic acid ester unit, the intermediate layer comprises a soft polymer i having an acrylic acid ester unit in the amount of 40-99.9 mass% and a multifunctional monomer unit in the amount of 0.1-5 mass%, and having a glass transition temperature of less than 25°C, and the outermost layer comprises a rigid polymer o, 80-100 mass% of which is a methacrylic acid ester unit; and the polymer particles II exhibit a weight average molecular weight of the soluble acetone content thereof of 60,000-90,000, and a volume average particle diameter as measured by the light-scattering method of 150nm or less, and have a single-layer structure in which the one layer thereof comprises a rigid polymer s, 80-100 mass% of which is a methacrylic acid ester unit.
