PURPOSE: To provide the titled resin compsn. having excellent mechanical strength and heat resistance and improved impact resistance, consisting of a styrene resin contg. an unsaturated dicarboxylic acid anhydride and glass fiber treated with an epoxy greige goods. n CONSTITUTION: A compsn. consists of a styrene resin contg. 5W35wt% unsaturated dicarboxylic acid anhydride and glass fiber treated with an epoxy greige goods. When the content of the unsaturated dicarboxylic acid anhydride is less than 5wt%, the heat resistance of the finally obtd. resin compsn. is not so improved, while when the content exceeds 35wt%, the impact resistance of the final resin compsn. is not so improved. As the glass fiber, those having a diameter of 9W13μ are suitable and those which are surface-treated with a silane coupling agent are preferred. Examples of the epoxy greige goods are those mainly composed of an epoxy resin such as bisphenol/epichlorohydrin epoxy resin or epoxyalkyl ester. n COPYRIGHT: (C)1984,JPO&Japio |
