Patent

CA 2106957

The description relates to novel organo(poiy)siloxanes of the general formula (I): (R1O)aHSiR2-aO[SiR2O]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.

Nouveaux organo(poly)siloxanes de formule générale (I) : (R1O)aHSiR2-aO[SiR2O]nSiR2R2, où R et R2 sont identiques ou différents et représentent un radical hydrocarboné monovalent, facultativement avec substitution; R1 est identique ou différent et représente lui aussi un radical hydrocarboné monovalent, facultativement avec substitution; n est un nombre entier de 2 ou plus; a est 1 ou 2. Les organo(poly)siloxanes sont utilisés comme additifs dans les substances qui peuvent être réticulées pour former des élastomères d'organopolysiloxane.
