Abstract

Well-defined poly(N-isopropylacrylamide) (PNIPAM) polymers with an oxazolone ring at the chain end have been synthesized by combining controlled radical polymerization and thiol-Michael addition "click" chemistry. First, PNIPAM was synthesized using reversible addition-fragmentation chain transfer (RAFT) polymerization to afford polymers of controlled molecular weight and molecular weight distribution (M_{n (1H NMR)} = 3200 g mol ^-1; PDI_SEC = 1.05). The chain end was quantitatively converted to a thiol by aminolysis. Then, the functional monomer vinyl azlactone (VDM) was quantitatively "clicked" onto the chain end using a thiol-Michael addition reaction. The polymers were reacted with a model amine in order to demonstrate the potential of these polymers for bioconjugation.
