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

Plastic compositions containing acrylonitrile-butadiene-styrene, an enhancing agent, hereinafter defined in the specification, and bis-phenoxy compounds having the formula ##STR1## WHEREIN Z is bromine, m is an integer having a value of 1-5 and m' is an integer having a value of 0-4, i is an integer having a value of 0-2 and i' is an integer having a value of 1-5, alkylene is a straight or branched chain alkylene group having from 1 to 6 carbon atoms and A is chlorine.

Flame retarded ABS polymeric compositions containing a mixed halo

Plastic compositions containing an acrylonitrile-butadiene-styrene polymer and bis-phenoxy compounds having the formula ##STR1## wherein Z is bromine, m is an integer having a value of 1-5 and m' is an integer having the value of 0-4, i is an integer having a value of 0-2 and i' is an integer having a value of 1-5, alkylene is a straight or branched chain alkylene group having from 1 to 6 carbon atoms and A is chlorine.

Plastic compositions

Plastic compositions, having utility in areas requiring flame retardancy, containing a three component system consisting of (1) acrylonitrile-butadiene-styrene polymer, (2) certain bis-phenoxy compounds having the formula: ##STR1## WHEREIN Z is bromine, m and m' are each integers having a value of 1-5 with the proviso that the total bromine atom content is from 6 to 10, and 'T' is a straight or branched chain carbon group having 1 to 4 carbon atoms, and (3) an enhancing agent, hereinafter defined.

Plastic composition comprising acrylonitrile-butadiene-styrene polymer,

Plastic compositions containing acrylonitrile-butadiene-styrene and bis-phenoxy compounds having the formula: ##STR1## WHEREIN Z is bromine, m and m' are each integers having a value of 1-5 and alkylene is a straight or branched chain alkylene group having 1 to 6 carbon atoms.

Plastic compositions containing acrylonitrile-butadiene-styrene and bis-phenoxy compounds having the formula ##SPC1## Wherein Z is bromine or chlorine, m and m' are integers having a value of 1-5, i and i' are integers having a value of 0-2, HBCA is a halo-branched chain alkylene group having from 1 to 6 carbon atoms and A is cyano, nitro, lower alkoxy, lower alkyl, fluorine, dialkylamino, phenyl, halo-phenyl, benzyl or halo-benzyl.

Plastic compositions containing acrylonitrile-butadiene-styrene polymer

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.
