ACRYLIC MULTISTAGE POLYMER COMPOSITION, METHACRYLIC RESIN COMPOSITION AND MOLDED ARTICLE

摘要

<P>PROBLEM TO BE SOLVED: To provide an acrylic multistage polymer excellent in handleability and blocking resistance, a methacrylic resin composition excellent in impact resistance and optical characteristics, and a molded article obtained by molding the methacrylic resin composition. Ž<P>SOLUTION: The acrylic multistage polymer composition containing 100 pts.mass of an acrylic multistage polymer pellet obtained by pelletizing an acrylic multistage polymer powder recovered from an acrylic multistage polymer latex obtained by emulsion polymerization and 0.01-0.2 pts.mass of a fine powder of hydrophobic silicon dioxide (to the 100 pts.mass of the pellet); the methacrylic resin composition having the acrylic multistage polymer composition and a methacrylic resin containing a methyl methacrylate unit; and the molded article obtained by molding the methacrylic resin composition are provided.
