Conductivity of crystalline polyacetylene prepared by phase-transfer dehydrochlorination of polyvinyl chloride

The conductivity of crystalline polyacetylene, both nonthermolyzed and ther molyzed at T less than or equal to 400 degreesC, remains unchanged upon ris ing the measurement temperature within 20-180 degreesC. The conductivity of the crystalline polyacetylene thermolyzed at temperatures above 400 degree sC tends to increase under the conditions indicated, and the conductivity o f the product of its pyrolysis at 700 and 800 degreesC varies in a complex manner.
