Abstract
Curable mixtures, comprising (a) a cycloaliphatic polyol of the formula I ##STR1## in which z is ##STR2## m is a number from 2 to 5, n is zero or a number from 1 to 10 and X is a direct bond or an aliphatic or cycloaliphatic radical, and (b) a prepolymeric polyhydroxy compound blocked by an aliphatic or cycloaliphatic diisocyanate, are advantageously suitable for producing adhesive bonds and seals having high tensile shear strengths.
