抄録

It is well known that a part of cis-1,4 double bonds in diene rubbers is converted to trans-1,4 double bonds during the vulcanization, which is called <i>cis-trans</i> isomerization. In this article, effects of compounding ingredients on the <i>cis-trans</i> isomerization were studied by using electron spin resonance (ESR) and solid-state <sup>13</sup>C-NMR results. The combination of ESR and NMR results revealed that the <i>cis-trans</i> isomerization was induced by a side reaction of the vulcanization by sulfur radicals. It was also found that the <i>cis-trans</i> isomerization was suppressed by zinc oxide. It is suggested that the reactivity of free sulfur radicals is enhanced by zinc oxide, resulting in the formation of C-S linkages on polymer chains.
