摘要：

The invention provides a fire retardant composition comprising a dispersion of a solid fire retardant such as melamine, ammonium polyphosphate or guanidine carbonate in a liquid organic polyisocyanate which contains dispersed polymer particles. The preferred content of solid fire retardant is from 10 to 100 % by weight and the preferred content of polymer particles is from 2 to 30 % by weight. The compositions of the invention are suitable for the preparation of flexible and rigid polyurethane foams.
