54 A crystalline thermoplastic resin composition comprises a rosin acid metallic salt and a crystalilne 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.
Divulgation d'une composition de résine cristalline thermoplastique comprenant un sel métallique acide de colophane et une résine cristalline thermoplastique. Facultativement, on peut y inclure un agent de compatibilité. Le sel métallique acide de colophane, qui agit comme agent de nucléation des cristaux, accroît la vitesse de cristallisation de la résine cristalline thermoplastique et permet la formation de fins cristaux de résine. La composition de résine cristalline thermoplastique peut donc se cristalliser à haute vitesse et produire des objets moulés ayant d'excellentes propriétés mécaniques et/ou optiques.
