ABSTRACT:
An improved synthetic resin composition is provided that consists essentially of 100 parts by weight of a resin component composed of 50 to 99 (preferably 50 to 90) parts by weight of a melt-processable polyester that does not form an anisotropic melt phase and 1 to 50 (preferably 10 to 50) parts by weight of a liquid crystal polyester that is capable of forming an anisotropic melt phase, to which has been added 0.01 to 0.5 part by weight of a phosphorus compound. The presence of the phosphorus compound has been found to facilitate the fibrillation of the liquid crystal polyester component during molding so as to form fibrils within the resulting molded article having an aspect ratio of 6 or more. The resulting molded article accordingly exhibits significantly enhanced mechanical properties.
