Co-oligomerization without initiator of α-bromoacrylic acid and 2-oxazoline monomers

Add time:07/31/2019    Source:sciencedirect.com

Zwitterion copolymerization without initiator of α-bromoacrylic acid as an electrophilic monomer with 2-methyl-2-oxazoline or 2-ethyl-2-oxazoline as a nucleophilic monomer was investigated. The copolymerizations were performed under various experimental conditions. Copolymers were characterized by i.r. and 1H-NMR as well as elemental analysis. Molecular weights were between 800 and 2300 g mol−1 by vapour pressure osmometry. There were also studies of the effects of solvent polarity on the yield and on the copolymer composition.
