Abstract:
A molding compound comprisinga reinforcing fiber having average fiber length of 6 mm or greater; a non-fibrous filler; and an unsaturated polyester resin comprising an unsaturated monomer and a polymer, the polymer comprising a hydroxyl component and a carboxylic component, wherein the hydroxyl component comprises a monomeric diol or triol and a polymeric polyol, wherein the polymeric polyol has a number average molecular weight of 200 to 4000, and is selected from the group consisting of polyether diols, polyether triols, polyester polyols and combinations thereof, and the carboxylic component comprises at least one compound selected from the group consisting of unsaturated carboxylic diacids, unsaturated carboxylic anhydrides, unsaturated carboxylic diesters, and mixtures thereof,wherein the polymeric polyol is present at a level of 1 to 30 weight percent, based on the total weight of the hydroxyl component and the carboxylic component.
