Abstract

Glass-fiber-reinforced molding compositions of reduced flammability consisting of (A) a linear saturated polyester resin, (B) from 10 to 60 per cent by weight of glass fibers and (C) from 3 to 30 per cent by weight of a flame retardant. The compositions contain from 2 to 20 per cent by weight, based on the total weight of the molding composition, of a particulate water-insoluble silicate having a bulk density of more than 100 g/l, which prevents dripping of the composition when in contact with an open flame.
