  A normally liquid, stable polymer/polyol composition which imparts improved combustion resistance to polyurethane foams prepared therefrom while retaining satisfactory foam tensile properties are formed by polymerizing in the presence of a free radical catalyst and in the essential absence of an alkyl mercaptan, (1) from about 25 to about 60 weight percent of an ethylenically unsaturated monomer or monomers, for example, a mixture of acrylonitrile and styrene in weight ratio respectively of 25:75 to 0:100, dissolved or dispersed in (2) from about 40 to about 75 weight precent of a polyol comprising a base polyol having a hydroxyl number of less than about 150, wherein the polymer is characterized by a crosslinking coefficient of less than 55 and an intrinsic viscosity of at least 0.30. The resulting polymer/polyol composition is treated to reduce the product viscosity to essentially the indigenous system viscosity in polymer/polyol compositions of this type.
