Abstract
Functionalized diorganopolysiloxanes containing alkoxy endgroups, well adapted for the formulation of single-component cold-vulcanizable elastomer compositions therefrom, are prepared by reacting an .alpha., .omega.-dihydroxydiorganopolysiloxane oil with a polyalkoxysilane in the presence of a catalytically effective amount of lithium hydroxide.
