权利要求: I claim:1. A liquid flame resistant composition comprising from about 0.20 to about 5 percent by weight of a triaryl or trialkyl phosphate, from 2 to about 10 percent by weight of a chlorinated polyphenyl, the remainder being a polymerized olefin fluid containing at least 30 carbon atoms.2. The composition of claim 1 wherein the said polymeric olefin has from about 30 to about 100 carbon atoms.3. The composition of claim 1 wherein the polymeric olefin is a decene trimer.4. The composition of claim 1 wherein said chlorinated polyphenyl is chlorinated biphenyl containing from 1 to about 5 chlorine atoms per molecule.5. The composition of claim 4 wherein the chlorinated biphenyl contains about 2 chlorine atoms per molecule.6. The composition of claim 1 wherein the aryl group is a cresyl group.7. The composition of claim 4 wherein the alkyl group is butyl.8. The composition of claim 1 wherein said chlorinated polyphenyl is present to the extent of from about 2 to about 7 percent by weight thereof.9. The composition of claim 1 wherein said triaryl or trialkyl phosphate is present to the extent of from about 0.5 to about 5 percent by weight thereof.10. The composition of claim 1 wherein said polymeric olefin is a mixture of decene trimers and tetramers, said chlorinated polyphenyl is a biphenyl containing about 30 percent chlorine and said triaryl phosphate is tricresyl phosphate.11. The composition of claim 1 wherein said polymeric olefin is a substantially decene trimer, said chlorinated polyphenyl is a mixture thereof and said phosphate is a mixture thereof.12. The composition of claim 11 wherein the mixture of chlorinated polyphenyls is a mixture of a chlorinated biphenyl and a chlorinated terphenyl and the mixture of phosphates is a mixture of tricresyl phosphate and tributyl phosphate.
