✦ Synopsis

Euide~,:e is #neunted that burning polyme[hyI metkaerylate and po~yoaymethylene do no~ react ch,mi¢ally rvitlt the gas around them, but merely vapome it, the hoar o! the surrouncIi~g diflusiott [lames, The pyrolysis products oxidize subsequenffy in the flames. Polyethylene probab.fy bu~ similarly, but Tenon may react directly toitk ozyge#. The t~vo-stage b,,ming o~ polymen which gasi/y mevdy by heating might be inhibited at either stage--in the con-de~ed phase, or in the ~arae.-.and the mode o/action o/some known inhibilors is i:westi. gated, It is shown that chlorine substituted in polyethylene inhibits by a/tectittg the pyrolysis o/the ¢oademed phase, but tl, e pair o/reactants, antimony plus a tittle cl, lo~ine, poisons the tlrame, Bromine is more effective titan cl~lorine because bromine also poisons the flame.
