Patent

CA 2194638

The present invention relates to asymmetrical siloxy compounds of the formulae (see fig. I) or (see fig. II) wherein R1, R2 and R3 are independently selected from the group consisting of alkoxy radicals having from 1 to 8 carbon atoms; R4 is selected from the group consisting of alkylene groups having from 1 to 15 carbon atoms and arylene and alkyl substituted arylene groups having from 6 to 10 carbon atoms; R5 is selected from the group consisting of alkylene groups having from 1 to 15 carbon atoms, arylene and alkyl substituted arylene groups having 6 to 10 carbon atoms; y is 2 to 8; X is selected from the group consisting of (see fig. III), (see fig. IV) and (see fig. V) W is selected from the group consisting of (see fig. VI) and (see fig. VII) and Z is 1 to 8.

Composés siloxy asymétriques de formule I (voir fig. I) ou II (voir fig. II), où R1, R2 et R3 sont choisis indépendamment dans le groupe constitué de radicaux alcoxy de 1 à 8 atomes de carbone; R4 est choisi dans un ensemble constitué de groupes d'alkylène de 1 à 15 atomes de carbone ainsi que de groupes d'arylène et d'arylène avec substituant alkylique, possédant de 6 à 10 atomes de carbone; y est 2 à 8; X est choisi dans le groupe constitué de...(voir fig. III, IV et V). W est sélectionné dans le groupe comprenant...(voir fig. VI) et (voir fig. VII); Z est 1 à 8.
