10,654 POLYESTER COMPOSITES ABSTRACT OF THE INVENTION This invention provides a reinforced polyester composition containing therein an unsaturated thermosetting polyester resin and alumina trihydrate particles treated on their surfaces with a silane, its hydrolyzates or resulting condensate. The silane has the following general formula: Image wherein R can be any divalent organic group which is either oxygen or carbon bonded to the silicon atom; RI is one or more 1,2-alkylene groups each containing at least 2 carbon atoms and typically not more than about 4 carbon atoms; RII is hydrogen, alkyl, acryloxy or an organofunctional group; a is a number from 4 to 150; and X is a hydrolyzable group. The reinforced polyester compositions have beneficial utility in molded thermoset articles such as automobile fenders, dash-boards and the like. S P E C I F I C A T I O N
