ABSTRACT:
Disclosed is a styrene-based resin composition which comprises (a) 100 parts by weight of styrene-based polymer having a high degree of syndiotactic configuration, (b) 0.01 to 15 parts by weight of at least one nucleating agent selected from an organophosphorus compound and a metal salt of an organic acid, and (c) 0.01 to 15 parts by weight of at least one component selected from a polyoxyalkylene compound, a fatty acid and a derivative thereof.
The composition can produce various molding products with excellent mold-releasing property, surface gloss, bending strength, bending modulus and heat resistance.
