HEAT-RESISTANT ACRYLIC RESIN COMPOSITION

PURPOSE:To obtain a heat-resistant acrylic resin composition having excellent transparency and impact resistance and physical properties required as a film. CONSTITUTION:50-98 pts.wt. acrylic resin mixture comprising (A) 1-100wt.% copolymer composed of 98-40wt.% methyl methacrylate, 1-30wt.% N- cyclohexylmaleimide and 1-30wt.% aromatic vinyl compound and (B) 99-0wt.% acrylic polymer containing 270wt.% methyl methacrylate are blended with (C) 2-50 pts.wt. multi-layer structural elastic material obtained by polymerizing 30-10 pts. wt. crosslinkable monomer mixture composed of methyl methacrylate, one or more of 1-8C alkyl acid alkyl esters and another vinyl-based monomer copolymerizable with these compounds in the presence of 70-90 pts.wt. crosslinked acrylic acid ester-based copolymer prepared by polymerizing a mixture of one or more of 1-8C acrylic acid alkyl ester and styrene (derivative) with a polyfunctional monomer which is copolymerizable with these compounds and contains two or more carbon-carbon double bonds in one molecule.
