Abstract
Hyperbranched polymers having a plurality of at least two different types of functional groups are described. Specific embodiments include hyperbranched polymers having functional groups of a first type that are substantially uniformly distributed throughout the hyperbranched polymer molecule and a second type of functional group that is substantially uniformly distributed at the terminals of the hyperbranched polymer molecule. The hyperbranched polymers having different types of functional groups are synthesized by reacting one or more monomers having functional groups that are capable of reacting during a set of polymerization conditions to form a hyperbranched polymer, wherein at least one of the monomers contains latent functional groups that are not reactive during polymerization.
