Abstract:
The present invention provides dialkyl phosphorus-containing compounds, namely reactive mono-hydroxyl-functional dialkyl phosphinates in a blend with a phosphate compound, said blend serving as highly efficient reactive flame retardant blend in flexible polyurethane foam. The invention further provides fire-retarded polyurethane compositions comprising said the reaction product of the flame retardant blend with polyol and isocyanate foam forming components.

Claim (Index 16):
A flame-retardant blend comprising:\n (A) a phosphorus-containing polyol reaction product of the partial phosphorylation of a polyalcohol, which phosphorus-containing polyol reaction product comprises at least one phosphorus-containing group, of the formula (I-B): wherein:\n R 1  and R 2  are independently selected from a linear or branched alkyl group containing from 1 to 4 carbon atoms, \n n 1  is an integer equal to or greater than 1 and n 2  is one, with n 1 +n 2  being equal to or greater than 2, and \n Z 2  is a moiety derived from a branched polyol which has a valence of n 1 +n 2 , and is of the general formula: \n wherein R is selected from the group consisting of: and where each R 6  independently is H or is an alkyl of from 1 to 4 carbon atoms, x is \u22651, y is 2 or 3; z is an integer of from 2 to 5; and, m\u22651; and, (B) a phosphate compound.
