Abstract

Compositions comprising a silylated polymer and an adhesion promoter, the silylated polymer having an inorganic or organic backbone and at least two groups thereon selected from alkoxysilyl, aryloxysilyl, alkyloximinosilyl and silanol groups and the adhesion promoter being a silane adhesion promoter of the formula: ##STR1## R.sup.1 is a branched or cyclic alkylene group, an arylene group or an alkarylene group, any of which may be optionally interrupted by one or more ether oxygen atoms or a (poly)sulfide bridge, provided that R.sup.1 has at least 4 carbon atoms; R.sup.2 is an alkyl, aryl or alkaryl radical having 1 to 6 carbons; R.sup.3 is a C.sub.1 to C.sub.6 alkoxy group or a C.sub.3 to C.sub.5 ketoximato group; R.sup.4 is hydrogen, a hydrocarbon group, which may optionally be substituted, or a group which will thermally deblock to form an amine group containing the nitrogen atom to which it is attached; and z is 0 or 1.
