摘要 |
<p>Disclosed is a methacrylic resin cast plate which is comprised of 100 parts by weight of [I] polymethyl methacrylate or a methyl methacrylate copolymer containing at least 90% by weight of methyl methacrylate units and, dispersed therein, a graft copolymer [IV] obtained by graft-polymerizing a hard resin component [III] containing at least 90% by weight of methyl methacrylate units onto a crosslinked rubbery copolymer [II] containing at least 45% by weight of butyl acrylate units and having an average particle diameter of 0.1 to 1 mu m, the amount of the graft copolymer [IV] being 2 to 30 parts by weight as the amount of the crosslinked rubbery copolymer. The methacrylic resin cast plate has a high transparency and impact resistance.</p> |
