Abstract
NEW MATERIAL:Compounds represented by formulas I and/or II, wherein R1W3 are 1W8C (halo)alkyl, Z' is methyl or ethyl, m is 0 or 1 and n is 0W2.
EXAMPLE: Tris[di(chloroethoxy)phosphinyl(dimethyl)methyl] phosphate.
USE: Flame retardant which, when added, provides polyurethane foams which change little with the lapse of time and keep flame retardancy for a long time.
PREPARATION: The flame retardants represented by formulas I and/or II are prepared by oxidizing with peracetic acid or H2O2, the reaction product obtained by reacting a compound represented by the formula: (R1O)mPCl3-m with a tri(halo) alkyl phosphite represented by formula III, wherein T is (halo)alkyl, in acetone or methyl ethyl ketone. A flame-retardant polyurethane foam is obtained by adding 1W30pts.wt. of said flame retardant to 100pts.wt. of a polyol, and thereafter reacting the mixture with an organic polyisocyanate.
