Abstract (en)

Flame retarding and plasticizing compositions for vinyl-chloride polymers comprising (i) a first phosphat ester component containing at least one C6-12 alkyl diphenyl phosphate and (ii) triphenyl phosphate having proportions of (i) to (ii) in the range of 1.8:1 to 5.5:1 are stable homogeneous liquids at low temperatures when prepared by a process in which a phosphorus oxyhalide is reacted with an excess of an alkali metal phenate to form a mixture containing triphenyl phosphate and alkali metal phenate, and the alkali metal phenate in that mixture is reacted with a C6-12 alkyl phosphrordichloridate.
