Abstract
This invention provides a styrene copolymer resin having heat resistance and impact resistance. The resin is a moldable thermoplastic resin obtained by copolymerizing 3 to 70% by weight of a rubbery polymer and 97 to 30% by weight in total of styrene and methacrylic acid, provided that the proportions of styrene and methacrylic acid are 97 to 65% by weight and 3 to 35% by weight, respectively. The styrene and methacrylic acid are partly grafted to the rubbery polymer.
