ABSTRACT:
An improved synthetic resin composition is provided that consists essentially of 100 parts by weight of a resin component composed of in excess of 50 up to 99 parts by weight of a liquid crystal polyester resin (A) capable of forming an anisotropic melt phase, and 1 up to less than 50 parts by weight of a polyalkylene terephthalate resin (B), to which has been added 0.001 to 5 parts by weight of a phosphorus ester (C) (e.g., a pentaerythritol phosphite). The presence of the phosphorus ester in the specifically defined polymer blend has been found to greatly impede the formation of deleterious mold deposits, and to make possible the formation of quality molded articles on an expeditious basis having good mechanical properties.
