Abstract
Melamine-polyol dispersions comprising ethoxylated alcohols of specific structures are disclosed. Such dispersions maintain their stability under stationary conditions for at least 24 hours and are useful in the manufacturing of polyurethane foams. The resulted polyurethane foams display more evenly-distributed flame retardant properties.
