Abstract
The description relates to novel organo(poly)siloxanes of the general formula (I): (R.sup.1 O).sub.a HSiR.sub.2-a O[SiR .sub.2 O].sub.n SiR.sub.2 R.sup.2, in which R and R.sup.2 are the same or different and represent a monovalent, possibly substituted hydrocarbon radical; R.sup.1 is the same or different and represents a monovalent, possibly substituted hydrocarbon radical; n is a whole number of at least 2; and a is 1 or 2. The organo(poly)siloxanes are used as additives in materials which can be cross-linked to form organopolysiloxane elastomers.
