Synthesis, structure and properties of some hyperbranched polyesters

Abstract
A new approach to the controlled synthesis of hyperbranched polyesters, via copolymerisation of AB2 and B3 monomers, has been demonstrated. This technique allowed relatively easy production of new families of hyperbranched materials, circumventing the laborious and time-consuming syntheses required for their dendrimer analogues. Copolymerisation of AB2 monomers with a B3‘terminator core’ restricted the hyperbranched growth and allowed an experimental assessment of points made in an earlier theoretical treatment of the subject.
