The presented work is dedicated to creation of polymer composite materials, based on industrial epoxide "ED-20" and carbofunctional organosilicon oligomers (COSO) based on water glass (WG), COSO were created by reaction of catalytic co-oligomerization of trimethylsillilated WG with the organosilicon dimethylacrylate also of organocyclosiloxanes with the organosilicon methacrilate. By using of the reaction of co-oligomerization of the organosilicon monomers, containing epoxy or methacrylic grups, with the various siliconorganic heterocycles, the new carbofunctional oligomers have been synthesized.
