Summary
The objective of this work was to prepare films of poly(phenylene acetylene) from films of a precursor polymer, namely poly(a, a′-dibromoxylylene). This polymer was obtained by selective bromination of the vinylene groups of poly(phenylene vinylene) films in bromine/CHCl3. Pyrolytic dehydrobromination of the brominated films under argon atmosphere gave dark yellow films which showed about 65 wt% of desired phenylene acetylene units.
