Abstract
Compounds of general formula I ##STR1## wherein R.sup.2 is hydrogen unsubstituted C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkyl substituted by --OH, --CN or by --Si(OR.sup.3).sub.3-q R.sup.4.sub.q, or C.sub.2 -C.sub.6 alkenyl, PA0 R.sup.3 is C.sub.1 -C.sub.4 alkyl, or two radicals R.sup.3 together are C.sub.1 -C.sub.4 alkylene, PA0 R.sup.4 is C.sub.1 -C.sub.4 alkyl or phenyl, and PA0 q is from 0 to 2, and PA0 E is a radical of the formula ##STR2## wherein R.sup.5 is hydrogen or C.sub.1 -C.sub.4 alkyl and PA0 R.sup.6 is hydrogen, or PA0 R.sup.5 and R.sup.6 together are C.sub.4 -C.sub.8 alkylene, or and PA0 A is --(CH.sub.2).sub.r --O--, wherein r is 1,2 or 3, and p is 0 or 1, and PA0 Y is oxygen or sulfur; and wherein PA0 T is a radical --R.sup.9 --Si(OR.sup.3).sub.3-q R.sup.4.sub.q, a radical of the formula ##STR3## X is --S-- or --NH--, and Z is an organic radical derived from a polyisocyanate or polyisothiocyanate having at least 2 NCO or NCS groups, respectively, are suitable as adhesion promoters, especially for moisture-curing polyurethane resins.
