Patent ID: 7619054

Claim:
A dendrimer comprising: an initiator core derived from a conjugate addition product of an amino compound and an acceptor molecule; interior generations comprising repeating units radially attached to the initiator core; and an exterior of terminal functionality attached to the outermost generation, wherein the amino compound is ammonia or a compound represented by A—(NH 2 ) n wherein n is 2 to 8 and A is an n-valent hydrocarbyl radical providing carbon atom points of attachment for the —NH 2 groups of the amino compound, and the acceptor molecule is an activated α,β-unsaturated compound wherein X and Y are independently selected from the group consisting of C(O)R, —CO 2 R, —C(O)NR 1 R 2 , —P(O)(OR 1 )(OR 2 ), —P(S)(OR 1 )(OR 2 ), —S(O 2 )R, —S(O)R, —S(O 2 )(OR), —S(O)(OR), —CN, —CF 3 , and NO 2 or X and Y together form a group selected from the group consisting of: wherein R, R 1 , and R 2 are alkyl or aryl having 1 to 20 carbon atoms, and R 3 and R 4 are independently hydrogen or cyclic, acyclic, aromatic or aliphatic substituents with 1-10 carbon atoms, and n is 2 or 3.
