 The synthesis and characterization of alternating copolymers from co-monomer complexes of styrene (St) and 2, 3, 4, 5, 6-pentafluorostyrene (FSt) is described. Proton NMR experiments demonstrate the formation of complexes in bulk St/FSt mixtures even at relatively high molar ratios (Kcomplex=0.2 � 0.1). Reactivity ratio studies indicate that these complexes contribute to the 1:1 consumption of monomers and ultimate alternating structure as shown by kinetics and hetero-nuclear multiple bond correlation (HMBC) NMR spectroscopy respectively. The addition of solvent can disrupt these complexes;providing a variable by which the polymer structure can be fine-tuned to include gradient polymer structures. This approach to sequence controlled polymerization is extended to include functional monomers (eg. 4-azidomethyl styrene), which allow for post-polymerization orthogonal modification.Previous work in our group has focused on the �click� functionalization of hyperbranched polymers.The current study adopts this approach as an important access point to a library of well-defined and versatile linear polymer-supported organo-catalysts.
