ABSTRACT:
To provide a resin composition, in which a liquid crystal polymer is made into fiber in a molded article to exhibit an extremely high reinforcing effect which has not been available yet, and from which a molded article having an excellent mechanical strength can be manufactured in a stable manner. That is, a thermoplastic resin composition, wherein 100 parts by weight in total consisting of 99-50 parts by weight of a thermoplastic polyester resin (A) not forming an anisotropic molten phase and 1-50 parts by weight of a liquid crystal polymer (B) capable of forming an anisotropic molten phase is blended with 0.001-2.0 parts by weight of one or more kinds of compounds (C) selected from phosphorus oxoacid monoester and diester represented by the following formulae (I) and (II):in-line-formulae description="In-line Formulae" end="lead"?(X)nP(═O) (OR)3-n  (I)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?(X)nP(OR)3-n  (II)in-line-formulae description="In-line Formulae" end="tail"?wherein n is 1 or 2; X is a hydrogen atom, a hydroxyl group or a monovalent organic group and, when there are plural X's, they may be the same or different; and R is a monovalent organic group and, when there are plural R's, they may be the same or different.
