Abstract
Abstract Flame retardant polymeric compositions comprising a polymeric base, a flame-retarding amount of an additive of the structure WHEREIN X is halogen and Y and Y'' are independently selected from the group consisting of hydrogen, halogen, lower alkyl and C1 to C4 alkoxy, and a synergistic additive selected from the group consisting of antimony oxide and zinc borate. In addition to flame-retardant characteristics, these polymeric compositions exhibit improved melt flow and thermal processability.
