<p>PURPOSE:To provide the titled compsn. having excellent moisture resistance and moldability, consisting of a polyphenylene sulfide resin, a specified inorg. filler and a mixture of an organosilane and (modified) silicone oil. CONSTITUTION:100pts.wt. polyphenylene sulfide resin (A) having a repeating unit of the formula and a melt flow rate of 1,000 to 10,000g/10min as measured by the method according to ASTM D 1238-74 (316 deg.C, load: 5kg) is melt-kneaded with 25-400pts.wt. inorg, filler (B) having an aspect ratio of not higher than 9 (e.g., fused silica), 0.2-25pts.wt. mixture (C) of an organosilane (e.g., vinyltrimethoxysilane) and unmodified silicone oil (e.g., polydimethylsiloxane) and/or silicone oil modified with a functional group selected from the group consisting of hydroxyl, amino, carboxyl, epoxy, methacryloxy and mercapto groups and optionally other polymers and additives at 280 to 400 deg.C.</p> |
