Abstract:
1. A flame retardant plexifilamentary film-fibril strand consisting of at least one polyolefin, from about 0.5 to about 15 weight percent of ethylene maleic anhydride compatibilizer based upon the total weight of polyolefin composition, and at least one flame retardant selected from the group consisting of: a) a liquid resorcinol bis(diphenyl phosphate) of the general formula (1): wherein n has an average value of from about 1 to about 7; (b) a liquid bis-phenol A-bis(diphenyl phosphate) of the general formula (2): wherein n has an average value of from about 1 to about 2; (d) a solid phosphate ester of the general formula (4): wherein n has an average value of from about 1.0 to about 2.0 and X is a divalent arylene moiety bonded to both of the oxygen atoms of any one of hydroquinone, resorcinol, 4,4′-biphenol, bisphenol S, or bisphenol F, and wherein the phosphate ester is in the absence of halogen; (e) a liquid aromatic polyphosphate of the formula (5): and mixtures thereof.
