Abstract
Flame retardant compositions are provided containing at least one ester of a polyhaloaromatic acid and at least one polyolefin resin. The compositions may also contain one or more brominated and/or chlorinated compounds to provide additional flame retardancy, and other resins or engineering thermoplastics may be blended with the polyolefin. In addition to providing flame retardancy, the polyhaloaromatic acid esters are effective as processing and compatibilizing aids for the resin, and may also function as tackifiers, mold release agents, plastisole, adhesives, plasticizers, polymer additives, and aids in preventing melt fracture.
