Title:
THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE OF SAME
Document Type and Number:
WIPO Patent Application WO/2011/004892
Kind Code:
A1
Abstract:
Disclosed is a thermoplastic resin composition that has a high fluidity and crystallization temperature and maintains the desired physical properties, such as strength, in a molded article, thus making it possible to improve molding efficiency. Also disclosed is a molded article formed therefrom. The thermoplastic resin composition contains a plurality of thermoplastic resins each having a different melt viscosity and containing a unit constituted by an arylene group, and an ether group and/or carbonyl group. The thermoplastic resin composition contains at least a first thermoplastic resin, the melt viscosity of which is 150 to 1500Pa・s at a temperature of 400°C and a sheer rate of 1216s-1, and a second thermoplastic resin. If the melt viscosity ratio of the first thermoplastic resin and the second thermoplastic resin is between 1.5/1 and 10/1 (first resin/second resin) at a temperature of 400°C and a sheer rate of 1216s-1, fluidity and mechanical properties can be achieved at the same time, and it is possible to increase the crystallization temperature and shorten the molding cycle.
