Flame retardance properties of 1,3 propylene glycol based unsaturated polyester containing 40% styrene and 20% acrylonitrile were investigated. The polyester with 12% Br content is self-extinguishing while others with lower bromine contents burn slowly. The high decrease in mechanical strength due to the presence of bromine is highly compensated by acrylonitrile.
