ABSTRACT:
Polyaminohydroxyl compounds having molecular weights of from 200 to 20,000 and a functionality greater than 1 but less than or equal to 8 containing 0.165-16.5 wt. % amino and hydroxyl groups and 0.295-29.5 wt. % urethane and/or urea groups are produced by hydrolyzing the corresponding NCO prepolymer containing OH groups. The equivalent ratio of amino groups to hydroxyl groups in these polyaminohydroxyl compounds is from 99:1 to 0.1:99.9. Groups which are inert with respect to amines and isocyanates may optionally be present in the polyaminohydroxyl compounds in quantities such that the equivalent ratio of amine groups to inert groups is from 100:0 to 33.3:66.6 and the equivalent ratio of hydroxyl groups to inert groups is from 100:0 to 33.3:66.6. These polyaminohydroxyl compounds are useful in the production of polyurethanes. The polyaminohydroxyl compounds in which the difference between the sum of amino groups plus hydroxyl groups plus inert groups and the sum of hydroxyl groups plus inert groups is 2.+-.0.25 are particularly suitable for producing molded polyurethane articles by a RIM process.
