PCT No. PCT/FR92/00899 Sec. 371 Date Sep. 13, 1993 Sec. 102(e) Date Sep. 13, 1992 PCT Filed Apr. 22, 1992 PCT Pub. No. WO92/19667 PCT Pub. Date Nov. 12, 1992.The description relates to novel organo(poly)siloxanes of the general formula (I): (R1O)aHSiR2-aO[SiR 2O]nSiR2R2, in which R and R2 are the same or different and represent a monovalent, possibly substituted hydrocarbon radical; R1 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.
