CA 2210100

The invention relates to oxyalkylene-group-containing organosilicon compounds having units of the formula (see Fig. I) where R is identical or different, and denotes a monovalent halogenated or nonhalogenated hydrocarbon radical, X is identical or different and is a chlorine atom or a radical of the formula -OR1, where R1 denotes an alkyl radical which can be substituted by an ether oxygen atom, a is 0 or 1, b is 0, 1, 2 or 3, c is 0, 1, 2 or 3 and the total a+b+c ~ 4 and A is a radical of the formula (see Fig. II) where R2 signifies an unbranched or branched substituted or unsubstituted divalent hydrocarbon radical, which may or may not contain ether, amine, sulfide, ester, amide, carbonate, urea and urethane groups, B is identical or different, and denotes X, -NR2 1, -O-C(=O)-R1, -SR1 or a radical of the formula -NR3R2 [O-CH(CH3)-CH2]d [OCH2CH2]e [O(CH2)4]f OR4 (III), where X, R1 and R2 have the meanings given for these above, R3 is identical or different and is a hydrogen atom or has the meaning of R, R4 has the meaning of R3 or signifies a radical of the formula -C(=O)-R, -R2NR2 3, -NR3R2- -R2NR2 3H+X- d, e and f are an integer from 0 to 200, with the proviso that the sum d+e+f ~ 1 and B contains at least one radical of the formula (III) per polymer molecule.

L'invention concerne des composés organosiliciés contenant un groupe oxyalcénylène ayant des unités de formule (voir Fig. I) où R est identique ou différent, et correspond à un radical hydrocarboné monovalent halogéné ou non halogéné, X est identique ou différent et est un atome de chlore ou un radical de formule -OR1, où R1 correspond à un radical alkyle qui peut être substitué par un atome d'oxygène formant un pont éther, a est 0 ou 1, b est 0, 1, 2 ou 3, c est 0, 1, 2 ou 3 et le total a+b+c ~ 4 et A est un radical de formule (voir Fig. II) où R2 est un radical hydrocarboné divalent ramifié ou non ramifié, substitué ou non substitué, qui peut ou non contenir des groupes éther, amine, sulfure, ester, amide, carbonate, urée et uréthane, B est identique ou différent, et correspond à X, -NR2 1, -O-C(=O)-R1, -SR1 ou à un radical de formule -NR3R2 [O-CH(CH3)-CH2]d [OCH2CH2]e [O(CH2)4]f OR4 (III), où X, R1 et R2 ont les significations données ci-dessus, R3 est identique ou différent et est un atome d'hydrogène ou a la signification donnée pour R, R4 a la signification donnée pour R3 ou est un radical de formule -C(=O)-R, -R2NR2 3, -NR3R2- -R2NR2 3H+X- d, e et f sont des nombres entiers de 0 à 200, à la condition que la somme d+e+f ~ 1 et que B contienne au moins un radical de formule (III) par molécule de polymère.
