    Abstract: POLYOL PRE-MIXTURE FOR MIXING FLAME-RETARDANT POLYURETHANE FOAM PLASTICS The disclosure relates to a storable polyol premixture for making flame-retardant polyurethane foam plastics consisting of a mixture of a polyester polyol or polyether polyol and an ammonium polyphosphate as a flame-retardant agent. The pre-mixture contains more particularly an ammonium polyphosphate which corresponds to the general formula (I) H(n-m)+2(NH4)mPnOn3n+1 (I) in which n stands for an integral average value of 100 to 1000, m stands for a whole number of up to n+2 and m/n stands for a value of about 1, has an acid number of 0.01 to about 5 mg KOH/g, contains 0.01 to 0.5 mass% water and 0.5 to about 15 mass% water-soluble fractions in water at 25.degree.C.
