Abstract

PURPOSE: To obtain a styrene resin sheet being excellent in a transparancy, a toughness, and a molding property, by stretching in two ways a sheet mixed with a polystyrene of a given molecular weight and a copolymer consisting of a maleic anthydried and a styrene.
CONSTITUTION: A sheet is mixed with 20W80wt% of a polystyrene, whose mean molecular weight ranges from 1.5×105W4.0×105, and 80W20wt% of a copolymer consisting of 5W50wt% of a maleic anthydride and 95W50wt% of a styrene, the sheet being stretched in each direction of two ways by 1.5W5.0-fold the length of the original to produce a styrene resin sheet. A favourable polystyrene is copolymer somprising the mixture of one, or two or more monomers, such as a styrene, an O- methylstyrene, an m-methylstyrene, a P-methylstyrene, an ethylstyrene, a dimethylstyrene, an a-methylstyrene, a P-chlorstyrene, a 2- and 4-dichlorstyrene, etc.
