摘要:
A fire retardant polyester composition is derived by inter- polymerisation from a system comprising a reactive adduct of hexachlorocyclopentadiene with maleic acid or anhydride, a polyhydric alcohol, a carboxylic acid or anhydride containing aliphatic carbon-to-carbon unsaturation, a styrence-type monomer, and a copolymerizable brominated neopentylacrylate.
