Title:
IMPACT RESISTANCE MODIFIER AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2005/097856
Kind Code:
A1
Abstract:
Disclosed is a resin composition having excellent impact resistance without deteriorating excellent transparency of a methacrylic resin. Specifically, an impact resistance modifier composed of a multilayered polymer having at least two layers, namely 100 parts by mass of an inner-layer polymer which contains an alkyl acrylate and a multifunctional monomer and has a mass-average particle size of 200-300 nm and 30-100 parts by mass of an outer-layer polymer which contains an alkyl methacrylate and has a Tg of 20-80&ring C, is blended into a methacrylic resin whose main constitutional unit is a methyl methacrylate.
