Abstract
A composition relating to an oligomeric alkoxy siloxane substituted with polymerizible epoxy or 1-alkenyl groups, and a process for the production of that composition, are disclosed. The process entails a hydrolysis-condensation oligomerization of an epoxy- or 1-alkenyl ether-functional trialkoxy silane, catalyzed by an ion exchange resin, and separation of the resin from the resulting oligomer.
