Patent ID: 7148369

Claim:
An organosilicon compound of formula (I) in which: n is between 20 and 25, k is between 0 and 100, i is an integer greater than or equal to 0, X 1 , X 2 and X 3 , which can be identical to or different from one another, are selected from the group consisting of saturated, linear or branched, C 1 to C 6 alkyls and hydrolyzable groups, at least one from X 1 , X 2 or X 3 representing a hydrolyzable group, and if k=0 and i=0, then Z represents an R 1 group, if k=0 and i≧1, then Z represents an —OR 1 , —OCOR 1 , —NR 1 R 2 , —COOR 1 , —CONR 1 R 2 or —SR 1 group or a halogen atom, if k≧1 and i=0, then Z represents an —R 1 , —COR 1 , —COOR 1 , —CONR 1 R 2 , —CF 3 or —(CF 2 ) j CF 3 group, j being between 1 and 10, if k≧1 and i≧1, then Z represents an —OR 1 , —OCOR 1 , —NR 1 R 2 , —COOR 1 , —CONR 1 R 2 , —SR 1 , —CF 3 or —(CF 2 ) j CF 3 group, j being as defined above, or a halogen atom, R 1 and R 2 , which can be identical or different, represent a hydrogen atom, an optionally substituted, saturated or unsaturated and linear or branched hydrocarbonaceous chain comprising from 1 to 24 carbon atoms, or an aromatic group; with the provisos that said organosilicon compound is other than a compound wherein: a) X 1 , X 2 and X 3 represent chlorine atoms, n is equal to 22, i is equal to 0, k is equal to 1 or to 3, and Z represents a —COCH 3 group, or b) X 1 , X 2 and X 3 represent chlorine atoms, n is equal to 22, i is equal to 1, k is equal to 2, and Z represents a —COOCH 3 group.
