| Abstract: | The deuterium-decoupled 100 MHz 1H-NMR spectra of 2,3-dideuteromethyloxirane and its polymer prepared with a lattice-disordered zinc dialkoxide were analyzed with consideration of the deuterium isotope effects on proton chemical shifts. The results of 1H- and l3C-NMR studies indicated that the initiator for methyloxirane polymerization catalyzed by the diethylzinc-alcohol system was a lattice-disordered zinc dialkoxide, from the aspect of stereoregularity of the polymers obtained. |
