Abstract
Vinyl- and alkoxy-functional organosilicon compounds with the general formula ##STR1## in which R denotes C.sub.1 and C.sub.4 alkyl and a is 1, 2, or 3, b is 0 or 1, and a+b is 2 or 3 are made by an exchange reaction between sym-divinyltetramethyldisiloxane and vinyltrialkoxysilane or tetraalkoxysilane. These novel vinyl- and alkoxy-functional organosilicon compounds exhibit a high condensation reactivity with the silanol group.
