ABSTRACT:
Normally flammable polyester resins (a) are rendered flame-retardant with reduced blooming or plate out tendencies and without loss in toughness or other properties in combination with (b) a flame retardant amount of decabromodiphenyl ether and (c) a flame-retardant synergist compound, by including a small amount of (d) an olefin polymer and/or an olefin copolymer. The compositions, which are useful per se for molding, extrusion, and the like, are, in addition, described in impact modified resin compositions and filled and/or reinforced modifications.
