Phosphate ester flame retardant mixture and foamed resins containing same
 A flame retardant composition, for use in flexible urethane foams, which contains about 5 to 95% of tris(monochloroalkyl, dichloroalkyl or mixtures thereof) phosphate and the remainder is a phenyl phosphate ester which is an alkylated triphenyl phosphate having an approximate average formula (R.sub.x ArO).sub.3 PO wherein x ranges from 1 to 2, each R is individually selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl and Ar is phenyl. Flexible urethane foam compositions containing 8 to 14 parts per 100 parts polyol of this composition have sufficient flame retardant properties to meet the Cal 117 test standard.
