説明
<jats:title>Abstract</jats:title><jats:p>The stereoregularity of poly(allyl vinyl ether), (poly[1‐(allyloxy)ethylene], <jats:bold>1</jats:bold>) was studied by both <jats:sup>1</jats:sup>H‐ and <jats:sup>13</jats:sup>C NMR‐spectroscopy at 6,34 tesla. Even at this field the <jats:sup>1</jats:sup>H NMR‐resonances severely overlap, thus hampering a reliable analysis. The situation is far better for the <jats:sup>13</jats:sup>C NMR‐resonances; here even hexad splittings could be observed. Relaxation time ratios of the backbone carbon atoms are consistent with a dipolar relaxation mechanism. The relaxation time for the racemic peak is longer than that for the meso peaks, which is in contrast with literature data for other polymers<jats:sup>7,8</jats:sup>. This deviating behaviour could be accounted for by the higher magnetic field used in our measurements.</jats:p>
