Polyphenylacetylene (PPA) is a variant of polymeric polyacetylene. Unlike polyacetylene, it is stable in air, which makes it easier to handle and investigate. Numerous studies have been conducted on this material. Syntheses have been made by different routes. Many catalysts have been used to achieve the polymerization, and an Rh catalyst was found to give high reactivity and provide stereoregular polymers. Electrical properties of undoped and doped PPA have been measured.
