PURPOSE:To obtain a styrene composition having good mold releasability and giving a molding which retains the mechanical properties inherent in styrene resins and is excellent in surface smoothness, sliding property, and transparency. CONSTITUTION:This composition comprises 100 pts.wt. styrene resin obtained by (co)polymerizing 100-60wt.% aromatic vinyl monomer and 0-40wt.% vinyl cyanide monomer and 0.05-5 pts.wt. polyorganosiloxane having a refractive index (nD) of 1.500-1.600. The composition has good mold releasability and gives a molding excellent in surface smoothness, etc. |
