CA 2164162

Polymers are prepared by condensation reaction between (A) the reaction product of a polyacid chloride (e.g. of the formula Image in which R represents -(CH2)n (where n has a value from 2 to 10) and an oxyalkylrene polymer having substituent groups condensible therewith (e.g. a polyoxyalkylene glycol) and (B) an organo-silicon compound having silicon-bonded groups of the general formula SiR(NHR1)mNH2. The organosilicon compound is preferably gamma-amino- propyltrimethoxysilane or gamma-aminopropyltriethoxysilane. Preferred polymers may be used in preparation of moisture curable sealants.
