Abstract: READILY FLAMMABLE POLYMERS ARE RENDERED FLAME RETARDANT BY THE ADDITION OF 8 TO 20% OF A BROMINE-CONTAINING POLYETHER WHICH IS A POLYMER OF A BROMO-SUBSTITUTED OXETANE OR 3 TO 20% OF THE BROMINE-CONTAINING POLYETHER AND 1 TO 15% OF AN ANTIMONY COMPOUND. WHEN ANTIMONY IS PRESENT THE COMBINED AMOUNT OF BROMINECONTAINING POLYETHER AND ANTIMONY COMPOUND IS AT LEAST 5% BY WEIGHT OF THE TOTAL COMPOSITION.

Abstract: FLAME RETARDANT COMPOSITIONS OF POLYMERS OF PROPYLENE ARE DESCRIBED. THE POLYMERS ARE RENDERED FLAME RETARDANT BY ADDITION OF 4-10% OF A CHLORINATED POLYISOBUTYLENE AND 0 TO 5% OF ANTIMONY TRIOXIDE, THE AMOUNT OF THE CHLORINATED POLYISOBUTYLENE AND ANTIMONY TRIOXIDE TOGETHER BEING 5-15% BY WEIGHT OF THE COMPOSITION.
