Abstract
Certain brominated polymers compounds are effective FR additives for combustible organic polymers. These FR additives include: i) a copolymer having styrene and 2,3-dibromopropylmaleimide repeating units; ii) a brominated polyester having aliphatically bound bromine; iii) an allyl ether of a ring-brominated novolac resin; iv) a 3-bromo-2-hydroxypropyl ether of a novolac resin; v) a 2,3-dibromopropyl ether of a cresol novolac resin; and vi) a brominated ROMP polymer or copolymer.
