The microwave-assisted cationic ring-opening polymerization of a soy-based 2-oxazoline monomer (SoyOx) was investigated. Kinetic investigations of the SoyOx polymerization in both acetonitrile and without additional solvent revealed the formation of well-defined poly(2-oxazoline)s with fatty acid side chains in a living manner. The living cationic ring-opening polymerization of bulk SoyOx reached full conversion within 8 minutes. The unsaturated bonds of the fatty acids are unaffected by the applied polymerization procedure. In addition, it was demonstrated that these double bonds can be used to cross-link the soy-based poly(2-oxazoline)s under UV-irradiation.
