ABSTRACT:
Thermoplastic blends of polyurethane polymers, chlorinated polyethylene polymer, optionally polyethylene resins and antimony trioxide, and a flame retardant selected from 1,2,3,4,7,8,9,10,13,13,14,14-dodecachloro-1,4,4a,6a,7,10,10a,12a-octahydro -1,4:7,10-dimethanodibenzocyclooctane, 1,2,3,4,5,6,7,8,10,10,11,11-dodecachloro-1,4,4a,4b,5,8,8a,9a-octahydro-1,4 :5,8-dimethanodibenzofuran, 6-(1',4',5',6',7',7'-hexachloronorborn-5'-en-2'-yl)-1,2,3,4,10,10-hexachlo ro-1,4,4a,5,6,7,8,8a,-octahydro-1,4:5,8-dimethanonaphthalene, and 6-(1',4',5',6',7',7'-hexachloronorborn-5'-en-2'-yl)-1,2,3,4,10,10-hexachlo ro-1,4,4a,5,6,7,8,8a-octahydro-1,4-methanonaphthalene, are flame resistant and also essentially retain the good physical properties of a polyurethane-chlorinated polyethylene polymer blend not containing a flame retardant.
