Claims
- 1. A flame-retardant resinous composition comprising a thermoplastic organic polymer selected from the group consisting of polyolefins and vinyl chloride polymers and a flame-retarding amount of 1,1,2,3,4,4-hexabromobutene-2.
- 2. A flame-retardant resinous composition as set forth in claim 1 that contains 5 percent to 50 percent, based on the weight of the polymer, of 1,1,2,3,4,4-hexabromobutene-2.
- 3. A flame-retardant resinous composition as set forth in claim 1 that contains 10 percent to 25 percent, based on the weight of the polymer, of 1,1,2,3,4,4-hexabromobutene-2.
- 4. A flame-retardant resinous composition as set forth in claim 1 wherein the 1,1,2,3,4,4-hexabromobutene-2 is a mixture of isomers containing about 90 percent of the trans isomer and 10 percent of the cis isomer.
- 5. A flame-retardant resinous composition as set forth in claim 1 wherein the organic polymer is a polyolefin.
- 6. A flame-retardant resinous composition as set forth in claim 5 wherein the organic polymer is polyethylene.
- 7. A flame-retardant resinous composition as set forth in claim 5 wherein the organic polymer is polypropylene.
- 8. A flame-retardant resinous composition as set forth in claim 1 wherein the organic polymer is polyvinyl chloride.
