Abstract: METALLIC IRON IS USED AS AN INGREDIENT OF THE POLYMERIZATION RECIPE TO IMPROVE THE MELT FLOW OF A POLYMER, PREPARED BY POLYMERIZING AT LEAST ONE VINYLIDENE MONOMER, E.G., STYRENE, IN THE PRESENCE OF A HALOGENATED FLAME RETARDANT. A PREFERRED EMBODIMENT OF THE INVENTION IS THE IMPROVEMENT OF THE MELT FLOW OF A FOAMABLE POLYMER PREPARED BY SUSPENSION POLYMERIZATION, WITH THE CONSEQUENT IMPROVEMENT OF THE DIMENSIONAL STABILITY OF A SELF-EXTINGUISHING FOAM PREPARED THEREFROM.

Abstract: 1. A SELF-EXTINGUISHING COMPOSITION COMPRISING (A) A THERMOPLASTIC POLYMER OF ETHYLENTICALLY-UNSATURATED MONOMERS COMPOSED OF AT LEAST 70 MOLE PERCENT PROPYLENE AND (B) A FLAME RETARDANT AMOUNT OF A MIXTURE OF (1) A HEXABROMOCYCLODODECANE HAVING A MELTING POINT ABOVE 200* C. AS INDICATED BY THE MAXIMUM ENDOTHERM DETERMINED BY DIFFERENTIAL SCANNING CALORIMETRY AND (2) ANTIMONY BTRIOXIDE, THE AMOUNT OF THE HEXABROMOCYCLODODECANE COMPONENT BASED ON THE TOTAL WEIGHT OF THE COMPOSITION BEING FROM ABOUT 1 TO 6 WEIGHT PERCENT AND THE RATIO OF SAID COMPONENT TO ANTIMONY TRIOXIDE VARYING FROM ABOUT 0.5 TO ABOUT 5.
