摘要： This invention relates to urethane linked hydroxy aromatic amines and to a process for producing such urethane linked hydroxy aromatic amines. The compositions are formed by initially reacting one equivalent aromatic diisocyanate with one equivalent of an alkylene polyol under conditions such that only one of the isocyanate groups reacts with one hydroxyl group of the polyol. Conditions are controlled such that only the urethane linked hydroxy aromatic isocyanate is formed. Then, the resulting urethane linked hydroxy aromatic isocyanate is hydrolyzed to form the amine.

摘要： This invention relates to a solvent-free process for producing polyurethane/urea elastomers wherein an aromatic diisocyanate is reacted with a compound having active Zerewitinoff hydrogen atoms and an aromatic diamine chain extender. The improvement for producing urethanes having a wide range of properties comprises including a urethane-linked diisocyanate in the polyurethane urea elastomer. The urethane-linked diisocyanate is one that is formed by reacting toluenediisocyanate or substituent thereof with a short chain diol under conditions such that the urethane linked diisocyanate comprises two equivalents isocyanate per equivalent diol.

摘要： This invention relates to urethane linked mixtures of 2,4-and 2,6- toluenediisocyanates (ULTDI dimers) having low melting points and to a method of forming these systems. The urethane linked toluenediisocyanates containing from 45-90% of the 2,4- and 10-55% of the 2,6- isomer by weight are formed by reacting two moles of an appropriate isomer mix of toluenediisocyanate, with one mole of a specific alkylene glycol, e.g., 1,2-butanediol, diethylene glycol or dipropylene glycol under conditions such that essentially only one of the isocyanate groups on a toluenediisocyanate molecule reacts with a hydroxyl group of the glycol. Conditions are controlled such that the urethane linked toluenediisocyanates are formed. The resulting product, which has two unreacted isocyanate groups, is suited for producing a variety of elastomers including polyurethane polyurethane/urea or polyurea elastomers.
