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