Abstract
Abstract An improved fire retardant polyester polymer system and composition comprising an interpolymer of a reaction product of hexachlorocyclopentadiene, a polyhydric alcohol, a carboxylic acid containing aliphatic carbon-to-carbon unsaturation, a styrene-type monomer, maleic acid or anhydride and a copolymerizable brominated neopentylacrylate comonomer.
