Abstract
(EN)
[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.

L'invention aborde le problème consistant à fournir une composition de résine qui relaxe l'anisotropie, tout en conservant la structure cristalline dérivant de la cristallinité liquide même après avoir été moulée pour donner un article moulé par un traitement à l'état fondu, par application d'un cisaillement, et refroidie, puis fondue sans application d'un cisaillement et de nouveau refroidie, et qui présente une structure et des propriétés isotropes du point de vue macroscopique. L'invention concerne à cet effet une composition de résine qui contient une résine de polyester cristal liquide (A) qui contient un motif constitutif (I) dérivant d'un acide hydroxycarboxylique, un motif constitutif (II) dérivant d'un composé diol et un motif constitutif (III) dérivant d'un acide dicarboxylique, et une résine (B) qui est différente de la résine de polyester cristal liquide (A) ; cette composition de résine étant caractérisée en ce que l'image de diffraction aux rayons X de la composition de résine, telle que mesurée après fusion, satisfait à une condition particulière.
