Abstract: The present invention is directed to a process for the production of an isocyanate which is both stable and liquid at room temperature comprising reacting pure diphenylmethane diisocyanate or crude diphenylmethane diisocyanate with the monoallyl ether of trimethylolpropane at a temperature of from 20.degree. to 110.degree. C., in such a ratio that the resultant product has an isocyanate group content of from 20 to 30%, by weight, and the product resulting therefrom.

Abstract: The present invention relates to a modified polyisocyanate having improved compatibility with aliphatic hydrocarbon solvents comprising the reaction product of(a) an aliphatic biuret isocyanate having the formula ##STR1## and (b) about 0.05 to 0.5 mols per equivalent of isocyanate of an aliphatic monohydroxy alcohol having at least 8 carbon atoms.

Abstract: The instant invention is directed to novel low temperature, storage stable liquid diphenylmethane diisocyanates and to the method of their preparation. The diisocyanates of the instant invention are produced by reacting diphenylmethane diisocyanates having a specified 2,4'-isomer content with propylene glycol or poly-1,2-propylene ether glycols. It has been surprisingly found that the products of the instant invention are both stable and liquid at -5.degree. C for at least 48 hours. In fact, in many instances, the products of the instant invention show no tendency to crystallize even when stored at -22.degree. C for weeks.

Abstract: The instant invention is directed to novel low temperature, storage stable liquid diphenylmethane diisocyanates and to the method of their preparation. The diisocyanates of the instant invention are provided by reacting diphenylmethane diisocyanates having a specified 2,4'-isomer content with polyoxyethylene glycols having molecular weights of from 150 to 1500. It has been surprisingly found that the products of the instant invention are both stable and liquid at -5.degree. C for at least 48 hours. In fact, in many instances, the products of the instant invention show no tendency to crystallize even when stored at -22.degree. C for 100 hours.
