PURPOSE:To provide the title compsn. which has excellent resistance to heat and water and mechanical properties and is not colored by flame-retardant aid, by blending a specified resin mixture with glass fiber, an organohalogen flame retarder, Sb2O3 and an alkali or alkaline earth metal hydroxide. CONSTITUTION:A polyamide resin (a), obtd. by polycondensing m- xylylenediamine or a mixture thereof with not more than 40wt.% p- xylylenediamine with a 6-20C alpha,omega-straight-chain aliph. dicarboxylic acid, is mixed with 1-50wt.% nylon 66 (b) to obtain a resin mixture (A). 100pts. (by weight; the same applies hereinbelow) component A is blended with 10-150pts. glass fiber (B), 3-35pts. organohalogen flame retarder (C) (e.g., brominated PS), 3-35pts. Sb2O3 (D), 0.1-5pts. hydroxide of Group I alkali metal or Group II alkaline earth metal (E) [e.g., Ca(OH)2] and optionally, an inorg. filler, a stabilizer, a nucleating agent, a plasticizer, etc. (F). |
