CA 2274030
The invention relates to organosilicon compounds with at least three silicon atoms, consisting of units of the formula (I) RaSi(NR1C=ONR22)k(NR3C=ONR4)t/2YmOn/2[(CR52)s]r/2, where Y represents units of the formula (II) -SiR63-p-q(NR1C=ONR22)p(NR3C=ONR4)q/2, where R, R1, R2, R3, R4, R5 and R6 independently of each other can be either identical or different and represent a hydrogen atom or possibly substituted monovalent hydrocarbon radicals with between 1 and 20 carbon atoms; and where a, k, t, n, m, r, s, p and q have the meaning assigned to them in claim 1, under the provision that the sum of p + q is 3, the sum of a + k + t + m + n + r equals 4, the sum of m + r equals 0 or 1, and the organosilicon compound of the invention contains at least one unit of formula (I) where t is not equal to 0.
Composés organosiliciques comportant au moins trois atomes de silicium, constitués de motifs de formule (I) R¿a?Si(NR?1¿C=ONR?2¿¿2?)¿k?(NR?3¿C=ONR?4¿)¿t/2?Y¿m?O¿n/2?[(CR?5¿¿2?)¿s?]¿r/2?, Y représentant des motifs de formule (II) -SiR?6¿¿3-p-q?(NR?1¿C=ONR?2¿¿2?)¿p?(NR?3¿C=ONR?4¿)¿q/2?, où R, R?1¿, R?2¿, R?3¿, R?4¿, R?5¿ et R?6¿ peuvent être identiques ou différents et représentent indépendamment l'un de l'autre un atome d'hydrogène ou des restes hydrocarbures monovalents éventuellement substitués comportant 1 à 20 atomes de carbone; a, k, t, n, m, r, s, p et q ont la signification donnée dans la revendication 1, à condition que la somme p + q soit inférieure ou égale à 3; la somme a + k + t + m + n + r soit égale à 4; la somme m + r soit égale à 0 ou 1, et le composé organosilicique de l'invention contienne au moins un motif de formule (I) où t est différent de 0.
