A glass fiber-reinforced thermoplastic polyester composition composed of (A) 100 parts by weight of a polyethylene terephthalate resin having an intrinsic viscosity, measured at 35 DEG C. in ortho-chlorophenol, of from 0.4 to 0.9 and comprising at least 80 mole %, based on the total acid component, of terephthalic acid or an ester-forming derivative thereof and at least 80 mole %, based on the total polyol component, of ethylene glycol or an ester-forming derivative thereof. (B) 5 to 200 parts by weight of glass fibers having an average length of at least 0.2 mm, (C) 0.05 to 3 parts by weight of a partially esterified montan wax acid having a neutralization value (NV) and a saponification value (SV) which are in the following relation 50</=NV</=110 (1) 100</=SV</=180 (2) 10</=(SV-NV)</=100 (3) and (D) at least one component selected from the group consisting of (D1) 0.01 to 3 parts by weight of a sodium or potassium salt of a monocarboxylic acid having 2 to 28 carbon atoms and (D2) 0.1 to 10 parts by weight of an ionic copolymer of an alpha -olefin and an alpha , beta -unsaturated carboxylic acid, said copolymer containing a mono- to tri-valent metal ion. |
