SYNTHESIS, STRUCTURE AND PROPERTIES OF SOME HYPERBRANCHED POLYESTERS

A new approach to the controlled synthesis of hyperbranched polyesters , via copolymerisation of AB(2) and B-3 monomers, has been demonstrate d. This technique allowed relatively easy production of new families o f hyperbranched materials, circumventing the laborious and time-consum ing syntheses required for their dendrimer analogues. Copolymerisation of AB(2) monomers with a B-3 'terminator core' restricted the hyperbr anched growth and allowed an experimental assessment of points made in an earlier theoretical treatment of the subject.
