The one-pot aminolysis/thiol-ene chain-end modification between a well-defined
trithiocarbonate-functionalized poly (N-isopropylacrylamide)(DP n= 13 and PDI= 1.06) and
N-phenyl maleimide has been investigated using triethylphosphite (P (OEt) 3) as a
coreagent. A quantitative chain-end functionalization has been obtained as shown by 1 H
NMR spectroscopy and MALDI-TOF mass spectrometry.
