    摘要: This invention relates to a phosphorus flame retardant composition formed from bringing together components comprising: a) a cyclic phosphanate flame retardant comprising (5-ethyl-2-methyl-2-oxido-1,3,2-dioxaphosphorinan-5-yl)methyl methyl ester of P-alkylphosphonic acid, and bis[(5-ethyl-2-methyI-2-oxido-1,3,2-dioxaphosphorinan-5-yl)methyl]ester of P-alkylphosphonic acid; and b) an alkylated triaryl phosphate ester flame retardant having a triphenyl phosphate (TTP) content of less than about 1 wt % based on the total weight of the alkylated triaryl phosphate ester. This invention further relates to the use of this phosphorus flame retardant composition especially for in polyurethane foams and textile applications.
