Abstract
Abstract Unsaturated polyester resins having improved fire retardant properties comprise a halogen-containing unsaturated polyester of a polycarboxylic compound and a polyhydric alcohol together with an additive mixture comprising iron or a compound of iron, copper or a compound of copper, and a compound of molybdenum. The unsaturated polyester resin may be copolymerized with an unsaturated monomer to prepare castings, laminated products, reinforced articles and the like having low burning rates, low smoke generations, and beneficial char formation in the presence of a flame.
