    摘要： Compounds containing hydroxyl groups, which are suitable for the polyisocyanate addition polymerization process, are prepared from polyurethane-polyurea and/or polyurea waste materials. These compounds are produced by reacting a finely divided polyurethane-polyurea and/or polyurea waste material with a low molecular weight diol and/or polyol (and optionally a higher molecular weight polyol) and a low molecular weight urea and/or carbamic acid ester. This reaction may be carried in either one stage or two stages. In the two stage process, the waste material and diol/polyol are reacted in a first stage at a temperature of from about 100 to about 260.degree. C. In the second stage, the amine-containing alcoholysis product obtained in the first stage is reacted with a low molecular weight urea and/or carbamic acid ester. In the single stage process, the polyurethane-polyurea and/or polyurea waste material is reacted with a low molecular weight diol and/or polyol in the presence of a low molecular weight urea and/or carbamic acid ester.

    摘要： Compounds containing alcoholic hydroxyl groups suitable as a starting material for the isocyanate polyaddition process by the alcoholysis of polyisocyanate polyaddition products are produced. Polyurethane urea or polyurea waste products having a molar ratio of urea groups to urethane groups of from 1:20 to 1:0 are heated in size reduced form to temperatures of from 120.degree. to 250.degree. C. together with B) polyhyhdric alcohols in the molecular weight range of from 62 to 250 in a ratio by weight of A:B of from 3:1 to 1:10. At least 10% of the polyhydric alcohol B put into the process is subsequently removed by distillation under reduced pressure. A total of up to 1000% by weight, based on the weight of polyurethane urea or polyurea waste A, of one or more polyhydroxy compounds having a molecular weight above 250 which is (are) not volatile under the distillation conditions may optionally be added to the mixture before and/or after removal of the excess alcohol B by distillation. The resulting compounds containing hydroxyl groups may be used as starting material for the production of polyurethane resins by the isocyanate polyaddition process.

    摘要： Polyamines containing primary amino groups are made by a one-shot process for the hydrolysis of prepolymers containing isocyanate end groups and having an isocyanate content of from 0.5 to 40 weight % with 0.75 to 40 mol of water per equivalent of isocyanate groups in the presence of very small quantities of sodium hydroxide in certain organic, polar solvents. The compounds containing isocyanate groups used for this process are isocyanate prepolymers (preferably containing urethane groups). Hydrolysis according to this process leads directly to the polyamines with elimination of carbon dioxide. These polyamines may be isolated by the usual methods and the removal of the small quantities of catalyst may advantageously be omitted. These polyamines are useful for the preparation of polyurethane(urea)s.
