Cationic ring opening polymerization of 2-ethyl-2-oxazoline with acetyl halide initiators

Kinetic investigations on the cationic ring opening polymn. (CROP) of 2-ethyl-2-oxazoline (EtOx) were conducted using acetyl chloride, acetyl bromide, and acetyl iodide as initiators. Various polymn. temps. ranging from 80 DegC to 220 DegC were applied under microwave irradn. The resulting polymn. mixts. were characterized with gas chromatog. (GC) and gel permeation chromatog. (GPC) for the detn. of monomer conversion and mol. wt. distribution, resp. [on SciFinder (R)]
