<p>A moisture curable composition is claimed comprising (a) a condensation product of a polyacid chloride with an alkylene or oxyalkylene polymer having substituent groups condensible therewith with an organosilicon compound having at least one silicon-bonded group -R(NHR<1>)mNH2 e.g. a material of the general formula <CHEM> wherein each R may be the same or different and represent a linking group, each R' represents a group R(NHR<1>)mNH2, a hydro- lysable group R", a group R"' or a group R'Si(OSiR<1>2)s-O- where R''' is a hydrocarbon group, m is from 0 to 10 and s is from 0 to 1500 and (b) a curative. Preferred materials are amino silanes in which R" is an oximo, alkoxy, alkenyloxy or alkoxyalkoxy group, R(NHR<1>)mNH2 is aminopropyl and m is 0. The aminosilane is preferably gamma -aminopropyltrimethoxysilane or gamma -aminopropyltriethoxysilane and the organic polymer is a polyoxyalkylene glycol.</p> |
