PROCESS FOR PREPARING A THERMOPLASTIC RESIN COMPOSITION HAVING A GOOD GLOSS

摘要

The thermoplastic resin composition is prepared by adding continuously 50-80 wt.% of a rubber latex composed of 40-80 wt.% rubber particle (A) having a particle diameter of 0.14-0.20 μm and 20-60 wt.% rubber particle (B) having a particle diameter of 0.25-0.35 μm, initiator and chain transfer into 50-80 wt.% monomer mixture composed of 68-75 wt.% aromatic vinyl compound and 25-32 wt.% vinyl cyanated compound. The composition has an excellent impact resistance and gloss property, and is useful for automobile parts, electric and electronic parts or OA equipment.
