Abstract
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.sup.1).sub.m NH.sub.2 e.g. a material of the general formula ##STR1## wherein each R may be the same or different and represent a linking group, each R' represents a group --R(NHR.sup.1).sub.m NH.sub.2, a hydrolysable group R', a group R'' or a group R'Si(OSiR.sup.1.sub.2).sub.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.sup.1).sub.m NH.sub.2 is aminopropyl and m is 0. The aminosilane is preferably .gamma.-aminopropyltrimethoxysilane or .gamma.-aminopropyltriethoxysilane and the organic polymer is a polyoxyalkylene glycol.
