Patent ID: 8372935

Claim:
A compound corresponding to the general formula (I): wherein: R 1 and R 2 , which are identical or different, represent, independently of one another, a linear or branched monovalent alkyl group, a cycloalkyl group, a (cycloalkyl)alkyl group, the ring being substituted or unsubstituted and optionally comprising at least one heteroatom, an arylalkyl, fluoroalkyl, substituted or unsubstituted aryl or R 11 R 12 R 13 Si group, where R 11 , R 12 , and R 13 are linear or branched monovalent alkyl groups; R 3 represents a hydrogen atom, a linear or branched monovalent alkyl group, a cycloalkyl group, an alkyl group substituted by a ring that is substituted or unsubstituted and that optionally comprises at least one heteroatom, an arylalkyl, fluoroalkyl, alkylamine, alkylguanidine or substituted or unsubstituted aryl group or an alkylalkoxysilane; R 4 represents a linear or branched alkyl chain containing 1 to 50 atoms some of them optionally being heteroatoms chosen from O, S and N; R 5 , R 6 and R 7 , which are identical or different, represent, independently of one another, a linear or branched alkyl group, an aromatic group, an alkoxy group or a trialkylsilyloxy group of formula (I′) below: R, R′ and R″, which are identical or different, represent, independently of one another, a linear or branched C 1 -C 12 alkyl group or an aromatic group; and on condition that: if R 3 is a hydrogen atom, then R 1 and R 2 are not, either of them, a linear monovalent hydrocarbon-based group; if R 1 and R 2 are each a cyclohexyl group, R 4 a linear propylene group and R 5 =R 6 =R 7 =OEt, then R 3 is not a hydrogen atom; and if R 1 and R 2 are each a cyclohexyl group, R 4 a linear propylene group and R 5 =R 6 =R 7 =OEt, then R 3 is not the group
