Abstract
When polystyrenes having peroxy bonds therein are charged into a polymerization system of methyl methacrylate series monomers, the said polystyrenes act as an opaquing agent and a polymerization initiator. The obtained opaque or translucent plate is splendid in optical and mechanical properties.
