-32- ABSTRACT The present invention relates to a process for preparing an alkoxy silyl-terminated material, which has at least one alkoxy group on at least one terminal end, said process comprising reacting in the presence of a catalytically effective amount of an organo-lithium reagent an alkoxysilyl-terminated first reactant with a second reactant having at least one end of its chain terminating in silanol groups. The alkoxy silyl- terminated material may have a variety of polymer backbone types such as silicone, polyurethane, polyamide and the like. These materials are intended to cure by either moisture cure or by dual moisture and photo cure mechanisms. The alkoxy silyl-terminated material is preferably an organopoly-siloxane having alkoxy groups at its terminal ends. The resultant alkoxy-terminated organopolysiloxanes are substantially stable materials as measured by preservation and maintenance of viscosity values (cps) over time.
