<p>A styrenic resin composition mainly comprising (A) 100 parts by weight of a styrenic polymer mainly having a syndiotactic structure and (B) 0.01 to 25 parts by weight of one or more nucleating agents selected from among (1) metal salts of organic acids having an average particle size up to 50 νm, (2) inorganic compounds having an average particle size up to 50 νm, (3) organophosphorus compounds having an average particle size up to 50 νm, and (4) metal salts of ionic hydrocarbon copolymers, and a process for producing styrenic resin moldings by molding said resin composition at room temperature to 200°C. The resin composition is adapted for injection molding and extrusion molding, and the resulting moldings have high crystallinity and excellent resistance to heat, solvents, chemicals, etc.</p> |
