Abstract
Polytrifluoromethylacetylene (PTFMA) was synthesized from trifluoromethylacetylene (TFMA) using a PdCl~2~/DMF catalyst solution or the anionic initiator nβbutyl lithium. Although PdCl~2~ proved to be an effective catalyst for the polymerization of TFMA, long reaction times and poor yields made characterization of the resultant polymer difficult. The use of nβbutyl lithium, on the other hand, resulted in high yields of PTFMA in relatively short reaction times. The results of thermal analysis and the effects of nβ and pβtype doping on the electrical conductivity of the polymer are discussed.
