A fiber-reinforced polymer composition containing resin components including (a) 30-90 weight % of a polyamide resin, and (b) 10-70 weight % of polyolefin + unsaturated carboxylic acid-modified polyolefin, based on the resin components; and, per 100 parts by weight of the total composition, (c) 5-50 parts by weight of glass fibers, and (d) additives including the following set of addivies: 0.1-1 parts by weight of N,N'-hexamethylene-bis (3,5-di-tert-butyl-4- hydroxy-hydrocinnamide); 0.1-1 parts by weight of triethylene glycol-bis [3-(3-tert-butyl-5-methyl-4-hydroxyphenyl) propionate]; and 0.1-1 parts by weight of pentaerythrityl- tetrakis [3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate]. An alternative set of additives are 0.1-2 parts by weight of N,N'-bis [3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionyl] hydrazine; 0.05-0.5 parts by weight of pentaerythrityl-tetrakis [3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate]; 0.05-0.5 parts by weight of distearyl-pentaerythritol diphosphite; and 0.15-1 parts by weight of distearyl-3,3'-thiodipropionate. The polymer composition has excellent thermal deformation resistance, chemical resistance and impact resistance as well as antifreeze resistance, moldability, Geer oven life and copper-contacted Geer oven life and is useful for producing containers such as automobile radiator tanks.
