INTERACTION OF POLYACETYLENE WITH PROTIC ACIDS IN AQUEOUS AND AQUEOUSALCOHOL-SOLUTIONS

The critical analysis of the interaction between polyacetylene and oxi dizing and nonoxidizing protic acids is presented. Polyacetylene as we ll as its composites with polyvinylbutyral were used in the experiment s. Polyacetylene in such composites was previously shown to have a low concentration of imperfection. The investigations pursued showed the same character of interaction of oxidizing protic acids with both poly acetylene and its composites; this interaction corresponds to the clas sical doping process. Interaction of polyacetylene composites with non oxidizing protic acids results in cis-trans-isomerization only and is not related to doping of polyacetylene. It is suggested that the key f actor defining the differences observed is the content of imperfection in polyacetylene.
