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.
