DESCRIPTION:Living radical polymer synthesis enables novel and interesting
  polymer architectures to be synthesized with relative ease. One such poly
 mer design is the core cross-linked star polymer (CCS polymer). This polym
 er has received much attention from a synthetic point of view\, but the rh
 eology of these polymers has not been characterised in detail.\n\nThis stu
 dy presents the results of a rheological study of various CCS polymer solu
 tions covering a range of different architectures and flow conditions. The
  polymer solutions have been shown to give an almost Newtonian response up
  to relatively high molecular weights and concentrations. At very high con
 centrations and molecular weights\, the response becomes more polymeric in
  its nature. It is hoped that this relatively preliminary work will provid
 e some insight into the potential application of these polymers which coul
 d include such areas as the film forming component of paint\, rheology mod
 ifiers for plastics processing and drug delivery agents among many other p
 ossibilities.
