PURPOSE: To obtain the titled composition, containing a copolymer consisting essentially of a specific polymerizable monomer and methyl methacrylate and suitable for a full molding method without damaging expandability and moldability and emitting black smoke and soot in burning. n CONSTITUTION: A resin composition obtained by polymerizing (A) 3W90wt.% polymerizable monomer expressed by the formula (R 1 is H or methyl; R 2 is bifunctional organic group; R 3 is 6W20C alicyclic hydrocarbon; n is 0 or 1) (e.g. cyclohexyl methacrylate) with (B) 10W97wt.% methyl methacrylate and, as necessary, (C) ≤10wt.% other polymerizable monomers (e.g. styrene). n COPYRIGHT: (C)1989,JPO&Japio |
