Alkoxysilane polysulphide

Abstract

The invention relates to an alkoxysilane polysulfide, of formula (I): (R3O)3-n(R1)nSi—CH2—(R2)CH—Z—Sx—Z—HC(R2)—CH2—Si(R1)n(OR3)3-n  (I), in which: R1, which are identical or different, each represent a monovalent hydrocarbon group having from 1 to 18 carbon atoms; R2, which are identical or different, each represent a monovalent hydrocarbon group having from 1 to 4 carbon atoms; R3, which are identical or different, each represent a monovalent hydrocarbon group having from 1 to 12 carbon atoms, preferably from 1 to 6 carbon atoms; Z, which are identical or different, each represent a divalent hydrocarbon bonding group comprising from 1 to 16 carbon atoms; x is an integral or fractional number greater than or equal to 2; and n is an integer equal to 0, 1 or 2.
