Abstract
The 2-chloropropionamide derivative featuring an azido group is used as the initiator for the ATRP of N-isopropylacrylamide (NIPAM) with copper(i) chloride (CuCl) and tris[2-(dimethyl-amino)ethyl]amine (Me 6 TREN) to produce the PNIPAM end-functionalized with an azido group. Subsequently, the 'click' reaction between the azido end-group and acetylene derivatives is demonstrated to produce PNIPAM in which the end-groups are modified by the phenyl, 4-phenoxyphenyl, butyl, octyl, carboxylic acid, and hydroxymethyl groups. The resulting PNIPAM derivatives show a LCST that ranges from 34.8 to 44.6 °C depending on the introduced end-group.
