THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which contains no bleeding-out component, the mechanical properties of which are not deteriorated but which has improved fluidity and to provide molded articles made from the thermoplastic resin composition. SOLUTION: The thermoplastic resin composition is composed of 90-99.9 wt.% thermoplastic resin (a) and 0.1-10 wt.% fluidity improving agent (b) and further contains a resin additive (c) of 0.01-5 parts weight on the basis of 100 parts weight resin composition. Such a phase structure is observed by an electron microscope that the fluidity improving agent (b) particles of 0.5-200 nm particle size are dispersed in a phase of the thermoplastic resin (a). The interfacial tension between the thermoplastic resin (a) and the fluidity improving agent (b) is≥0.4 mN/m. COPYRIGHT: (C)2009,JPO&INPIT
