Abstract

Synthesis
of amphiphilic polysulfone graft copolymers by ‘‘Click’’ chemistry is
described.  First, a commercial PSU was
chloromethylated to give chloro-funtional PSU (PSU-Cl). Subsequently, chloride
groups were converted into azide moieties by nucleophilic substitution.
Hydrophilic poly(N,N-dimethylacrylamide) (PDMA) side chains were then attached
via a “grafting to” approach by using copper-catalyzed azide–alkyne
cycloaddition (CuAAC). Precursor polymer and the final amphiphilic copolymers were characterized by ¹H
NMR, FT-IR, GPC and contact angle measurements.

Keywords
