Hyperbranched poly(ester)s offer attractive features for applications in a number of areas, particularly as platforms for the support of controlled release actives in the agricultural and biomedical fields. Hyperbranched polymers are well-suited for controlled delivery because of high branching density and high end group content. This permits incorporation of an active agent either through physical entrapment or covalent bonding to end groups. Various endgroup functionalities can be obtained by appropriate choice of monomer stoichiometry, providing opportunities for different chemistry to attach beneficial substances. A series of hyperbranched poly(ester)s based on tri-functional alcohols (trimethylolpropane, glycerol) and diacids (adipic and succinic acid) with �OH and �COOH endgroups have been synthesized using nonlinear polymerization methodology. The resulting polymers were characterized using chromatographic, spectroscopic and thermal methods.
