Nitroxide Mediated Polymerisation of Thioacrylates and Their Transformation into Poly(acrylamide)s
One long-standing challenge in polymer science is the development of transformation reactions, in which the conversion of a specific functional group to another is targeted. For this purpose, a thioester polymer consisting of thioacrylate monomers has been prepared via nitroxide mediated polymerization and its kinetics studied for the first time. The copolymerization behavior of butyl thioacrylate with PFS was investigated in detail and compared to the copolymerization of butyl acrylate and PFS. Finally, a series of modification reactions were carried out using different amines and alcohols, in an attempt to transform the thioacrylate monomer into an acrylamide or acrylate, respectively. The established conditions allowed to obtain poly(acrylamides) via post-polymerization functionalization in a versatile and efficient way, that is believed to find wide use with polymer chemists.
