Title:
RESIN COMPOSITION CAPABLE OF RELAXING ANISOTROPY BY MELTING AND RESIN MOLDED ARTICLE FORMED OF SAID RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/090823
Kind Code:
A1
Abstract:
[Problem] To provide a resin composition which relaxes anisotropy, while maintaining the crystal structure derived from liquid crystallinity even after being molded into a molded article by melt processing under the application of shear and cooled, and subsequently melted without application of shear and cooled again, and which has an isotropic structure and properties from a macroscopic viewpoint. [Solution] A resin composition according to the present invention contains a liquid crystal polyester resin (A) that contains a constituent unit (I) derived from a hydroxycarboxylic acid, a constituent unit (II) derived from a diol compound and a constituent unit (III) derived from a dicarboxylic acid, and a resin (B) that is other than the liquid crystal polyester resin (A); and this resin composition is characterized in that the X-ray diffraction of the resin composition as measured after melting satisfies a specific condition.
