PURPOSE:To obtain a plate for vacuum forming excellent in flexural elastic modulus, impact resistance, vacuum formability and surface smoothness. CONSTITUTION:This plate for vacuum forming is formed from a resin composition composed of 100 pts.wt. graft copolymer prepared by graft copolymerization of 96-70wt.% vinyl chloride monomer with 4-30wt.% alkyl (meth)acrylate polymer consisting essentially of an alkyl (meth)acrylate monomer having <=-20 deg.C second order transition point of a homopolymer thereof and having 50-95wt.% crosslinking ratio and 2-15 pts.wt. acrylic processing aid having 1000000-5000000 weight-average molecular weight. |
