Zusammenfassung:LOW TEMPERATURE, STORAGE STABLE MIXTURES OF POLYESTER PREPOLYMERS AND FLOW MODIFIERS There are provided low temperature, storage stable, liquid mixtures of (1) isocyanato-containing prepolymers obtained from the reaction of linear and/or slightly branched polyols and a polyisocyanate characterized by a methylene group (CH2) bonded to two benzenoid nuclei, and (2) a non-hydroxyl-containing flow modifier which is compatible with the said prepolymer. Novel liquid mixtures thus prepared exhibit little tendency to crystallize or phase separate when stored for prolonged periods of time, i.e., well below room temperature for several days.
