Beschreibung
Zusammenfassung:	A crystalline thermoplastic resin composition comprises a rosin acid metallic salt and a crystalline thermoplastic resin. Optionally, a compatibilizing agent may also be included. The rosin acid metallic salt, which acts as a crystal nucleating agent, increases the crystallization rate of the crystalline thermoplastic resin and enables the formation of fine crystals of the resin. Thus, the crystalline thermoplastic resin composition can crystallize at a high rate, and provide molded articles having excellent mechanical properties and/or optical properties.
