摘要： Ether-linked amine-terminated polyesters are produced by reacting (1) a polyester polyol in which substantially all of the hydroxyl groups have been replaced with good leaving groups with (2) an aminoalcohol and/or aminothiol and (3) a deprotonating agent. The aminopolyesters obtained by this process are characterized by excellent reactivities over a wide range of molecular weights and functionalities.

摘要： Storage stable, liquid prepolymers of diphenylmethane diisocyanate containing urea and/or biuret groups are prepared by reacting an aminocrotonate with a mixture of isocyanates having a specified diphenylmethane diisocyanate isomer content. These prepolymers have isocyanate group contents of from about 5 to about 30%.

摘要： Aliphatic and/or cycloaliphatic polyisocyanates containing allophanate groups are produced by reacting (a) a di- and/or polyisocyanate with aliphatic and/or cycloaliphatic isocyanate groups with (b) a hydroxy compound at a temperature of at least 150.degree. C. for no more than 90 minutes and then rapidly cooling the reaction mixture to a temperature of less than 100.degree. C. It is preferred that the reaction be carried out in the absence of oxygen. The products thus obtained are virtually colorless, have a relatively low viscosity and excellent storage stability.
