Star (dendritic) copolymers are copolymer with long polymer branches attached to central core
“Dendrimers are described as globular, nano-scale macromolecules consisting of two or more tree-like dendrons., emanating from a single central atom or atomic group called the core. They are comprised of branch cells that are the main building blocks of dendritic structures, that is, three-dimensional analogues of repeat units in classical linear polymers, that must contain at least one branch juncture, and that are organized in mathematically precise architectural arrangements, that give rise to a series of regular radially concentric layers. called generations (G) around the core. Dendrimers must contain at least three different types of branch cells including a core, interior cells, and surface or exterior cells. “
”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, which may end with a potentially reactive, or a potentially inert functional group called by those skilled in this particular art, the focal group. “
“On the other hand,
hyperbranched polymers are random highly
branched macromolecules usually obtained from a "one-shot" polymerization
reaction of an AB.sub.w type of monomer, that is .sub.nAB.sub.w.fwdarw.- - - (AB.sub.w).sub.n-
- - , where A and B represent mutually reactive functional groups of the
monomer. They are usually different from dendrons, in that, hyperbranched
macromolecules are considerably more architecturally variable in their
structure, have a lower degree of branching, and as materials, usually have a
high degree of polydispersity, in that, not all hyperbranched macromolecules of
the same hyperbranched polymer are of the same molecular weight or chain
length.”

-- block copolymers in which several polymer blocks are attached to a common core. Baker and Walbridge synthesized highly branched polyesters for coatings. (US Patent 3,669,939; June 13, 1972) Denkewalter, Jaroslav and Lukasavage developed a highly branched copolymer based on lysine units.
