INFLUENCE OF DEFECTS ON MECHANISM OF INTERACTION OF POLYACETYLENE WITH PROTONIC ACIDS

In the experiments standard polyacetylene and its blends with polyviny lbutyral were used. Previously, it was shown that polyacetylene in suc h blends contain fewer defects. These studies showed, that oxidizing p rotonic acids interact similarly with standard polyacetylene and its b lends. This interaction corresponds to the classical process of doping . Interaction of polyacetylene blends with non-oxidizing protonic acid s indicate only cis-trans isomerization PA with no associated doping. The assumption is made that principal factor determining these differe nces is content of defects in polyacetylene.
