Patent

CA 2703941

Extruded polymer foams are prepared using brominated fatty acids, an ester, amide or ester-amide of a brominated fatty acid, a glyceride of one or more brominated fatty acids, or a polymerized brominated fatty acid as an FR additive. The brominated FR additives unexpectedly are stable at the extrusion temperatures, and provide excellent flame retardancy to the foams.

L'invention porte sur des mousses polymères extrudées qui sont préparées à l'aide d'acides gras bromés, d'un ester, amide ou ester-amide d'un acide gras bromé, d'un glycéride d'un ou de plusieurs acides gras bromés ou d'un acide gras bromé polymérisé en tant qu'additif ignifugeant. Les additifs ignifugeants bromés sont étonnamment stables aux températures d'extrusion et confèrent une excellente ininflammabilité aux mousses.
