| titleOfInvention | Processes for preparing bis(urea-urethane) compounds |
| abstract | Processes for preparing bis(urea-urethane) compounds n n nwherein R 1 is alkyl, aryl, arylalkyl, or alkylaryl, R 2 is alkylene, arylene, arylalkylene, or alkylarylene, R 3 is alkylene, arylene, arylalkylene, or alkylarylene, and R 4 is hydrogen or alkyl, comprising: (1) first bring to a reaction temperature of about 20-125° C. a reaction mixture comprising monoalcohol reactant R 1 —OH and diisocyanate reactant OCN—R 2 —NCO, the monoalcohol being present in an amount of about 0.8-1.2 moles monoalcohol per mole diisocyanate, the monoalcohol and diisocyanate reactants being admixed in a solvent, the reactants and solvent being present in relative amounts of at least about 1 milliliter solvent per millimole diisocyanate, the reaction temperature continuing until reaction between the monoalcohol and the diisocyanate is complete; and (2) subsequent to step (1), adding to the reaction mixture diamine n n nwithout isolating the reaction product of step (1), thereby forming compound of the formula n nin desirably high yield and purity. |
