Abstract

The use of 2D homonuclear J-resolved 1H nuclear magnetic resonance (NMR) spectroscopy in the investigations of the methine region of poly(cyclohexene oxide) formed by polymerization of cyclohexene oxide employing the Union Carbide calcium-amide-alkoxide catalyst reveals the majority of the ring opening occurs by backside attack. Trimer molecular model were constructed using a numerical code with hydroxyl group chain termini in the equatorial positions. After minimization of each molecular model, vicinal coupling constants were calculated.
