group called the core.” (Specification 1.) “Dendrons are the smallest
constitutive elements of a dendrimer that have the same architectural
arrangement as the dendrimer itself, but which emanate from a single trunk
or branch.” (Id.) “[H]yperbranched polymers are random, highly branched
macromolecules usually obtained from a ‘one-shot’ polymerization reaction
of an ABw type of monomer, that is nABw→----(ABw)n------, where A and B
represent mutually reactive functional groups of the monomer.” (Id. at 2.)
“Multi-layered macromolecules” have a base macromolecule that is a
dendrimer or a hyperbranched polymer with additional layers of
macromolecules chemically bonded to the base macromolecule, the
additional layers of macromolecules being dendrimers, hyperbranched
polymers, or combinations of them. (Id.)
The specification describes “an alkylated amine functional
macromolecule comprising a base macromolecule covalently bonded to a
solid substrate wherein the base macromolecule is selected from the group
consisting of amine functional (a) dendrimers, (b) hyperbranched polymers,
(c) multilayered dendrimers, (d) multilayered, hyperbranched polymers,
(e) multilayered polymers of mixed dendrimer, and hyperbranched
multilayers. The amine functionality of the macromolecule is further
modified to provide alkylated amine functionality.” (Id. at 5.)
The specification states that silane bonding agents may be used to
bond the macromolecules to the substrate. (Id. at 2.) “[S]ilane bonding
agents . . . are any functional silane that comprises a hydrolyzable leaving
group that allows the reaction of the silane bonding agent with the solid
