As resin requirements and environmental concerns have increased, the development of polymeric flame retardants has occurred. Brominated polystyrenes are widely used as flame retardants for thermoplastic polyesters and polyamides. The incorporation of comonomers at low levels has improved the compatibility of polybromostyrenes with each of these resin systems as evidenced by scanning electron micrographs. The improvement in physical properties and the reductionin flammability of PBT and polyamides as a function of the comonomer type and concentration are explored in this paper.
