Disclosed are plastic compositions comprising (i) polystyrene; (ii) a bis-phenoxy compound of the formula ##STR1## wherein alkylene is a straight chain carbon group having 1 to 6 carbon atoms; (iii) a poly (brominated phenylene oxide); and (iv) an enhancing agent. Also described is a flame retardant additive composition for polystyrene plastic compositions comprising (i) said bis-phenoxy compound, (ii) said poly (brominated phenylene oxide), and (iii) said enhancing agent.

Flame retardant polystyrene plastic compositions

A flame-retarded poly(butylene terephthalate) composition comprised of poly(butylene terephthalate) and from about 5 to about 35 percent (by weight of total composition) of a condensation product derived from brominated phenol is disclosed.

Flame retarded poly(butylene terephthalate) composition

Disclosed is a novel, flame retarded, non-blooming nylon composition with excellent thermal stability. This composition is comprised of from about 5 to about 35 percent (by weight) of a condensation product derived from brominated phenol by the displacement of bromine from said phenol wherein: (a) said phenol is selected from the group consisting of tribromophenol, tetrabromophenol, pentabromophenol, and mixtures thereof; (b) said condensation product has a repeating structural unit of the formula ##STR1## WHEREIN A IS AN INTEGER OF FROM ABOUT 0 TO ABOUT 4, B IS AN INTEGER OF FROM ABOUT 0 TO ABOUT 2, C IS AN INTEGER OF FROM ABOUT 1 TO ABOUT 5, A PLUS B PLUS C EQUAL 5, Q is a monovalent bond from a carbon atom in the aromatic nucleus of said repeating structural unit to an oxygen atom bonded to an aromatic nucleus, and the polymeric units containing said repeating structural unit comprise at least 80 percent (by weight) of said product; (c) said condensation product contains from about 17 to about 31 percent (by weight) of elemental carbon, from about 0 to about 1.0 percent (by weight) of elemental hydrogen, from about 3 to about 8 percent (by weight) of elemental oxygen, and at least 60 percent (by weight) of elemental bromine; and (d) said condensation product has a molecular weight of at least 750, and one or more polymeric units containing at least four aromatic nuclei per unit comprise at least about 80 percent (by weight) of said product.

Flame retarded nylon composition

Acrylonitrile-butadiene-styrene polymer compositions are rendered flame retardant by the incorporation therein of an effective amount of decabromobiphenyl. The flame retardant composition has the added advantage of being stable against discoloration caused by light and/or ultraviolet radiation.
