Abstract
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.
Claims7
An extruded combustible polymer foam containing a flame retarding amount of a brominated fatty acid, an ester, amide or ester-amide of a brominated fatty acid, a glyceride of one or more brominated fatty acids, a polymerized brominated fatty acid, or a mixture of any two or more of the foregoing, and a melt flow promoter, wherein said combustible polymer is polystyrene, a styrene-acrylic acid copolymer, or a styrene-acrylonitrile copolymer or a mixture of two or more thereof.
An extruded combustible polymer molded article, the extruded combustible polymer molded article containing a flame retarding amount of a brominated fatty acid, an ester, amide or ester-amide of a brominated fatty acid, or a glyceride of one or more brominated fatty acids, a polymerized brominated fatty acid, or a mixture of any two or more of the foregoing, wherein said combustible polymer is polystyrene, a styrene-acrylic acid copolymer, or a styrene-acrylonitrile copolymer or a mixture of two or more thereof.
