Claim:
A dendritic polymer of generation n composed of: a central core § of valence m; generation chains branching around the core; an intermediate chain at the end of each bond around the core or at the end of each generation chain, where appropriate; and a terminal group at the end of each intermediate chain, wherein m represents an integer from 3 to 8; n represents an integer from 0 to 12, wherein the generation chains are represented by the formula: -A″-N< (C1″) wherein A″ represents an alkyl radical, an alkenyl radical or a alkynyl radical, each of which is optionally substituted by one or more substituents selected from -Alkyl, -Hal, —NO 2 —NRR′, —CN, —CF 3 , —OH, -OAlkyl, -Aryl, and -Aralkyl; and wherein R and R′, which are identical or different, each independently of the other represents a hydrogen atom or an -alkyl radical, an -aryl radical, or an -aralkyl radical, the intermediate chains, which are identical or different, are represented by formula -J-K-L- (C2) or -L″- (C2′) wherein J represents an oxygen atom, a sulfur atom or a radical —NR—; K represents an aryl, heteroaryl or alkyl radical, each of which is optionally substituted by a halogen atom or by —NO 2 , —NRR′, —CN, —CF 3 , —OH, an -alkyl radical, an -aryl radical, or an -aralkyl radical; L represents a hydrocarbon chain having from 1 to 6 chain members and optionally having one or more heteroatoms and/or optionally having one or more double or triple bonds, each of said chain members being optionally substituted by one or more substituents selected from —OH, —NRR′, and -Oalkyl; and R and R′, which are identical or different, each independently of the other represents a hydrogen atom or an -alkyl, -aryl, or -aralkyl radical; and L″ represents an -alkyl- chain having from 1 to 6 chain members, optionally substituted by one or more substituents selected from —OH, —NRR′, and -Oalkyl, where R and R′, which may be identical or different, each independently represent a hydrogen atom, an alkyl radical, an aryl radical or an -aralkyl radical; and the terminal group consists of the group of formula: wherein each of the radicals X is a methyl group, with the exception of the compound of formula: CH 3 —CH 2 —C[CH 2 O—C(OSiMe 3 )═CH—CH 2 —P(═O) —(OH) 2 ] 3 .
