Abstract
PURPOSE: To produce the titled resin having remarkably excellent impact resistance, by adding a graft-polymerizable elastomer in divided portions in graft- copolymerizing a mixture of a vinyl aromatic monomer and an unsaturated dicarboxylic acid anhydride.
CONSTITUTION: In graft-polymerizing a monomer mixture consisting mainly of 55W98wt% vinyl aromatic monomer (e.g., styrene) and 45W2wt% unsaturated dicarboxylic acid anhydride (e.g., maleic anhydride) in the presence of 5W 30pts.wt., per 100pts.wt. mixture, graft-polymerizable elastomer (e.g., cis-1,4-polybutadiene); 20W80% of the total monomers is added at the start of reaction and 80W20% of the total monomers is added during polymerization. It is possible to obtain the titled resin remarkably excellent in impact resistance having a more stable "salami structure" by adding the elastomer component in portions after the phase reversion of the elastomer.
