Anionic polymerization of tolane and of diphenylbutadi-yne☆

Abstract Tolane and diphenylbutadi-yne were polymerized in THF. The polymerizates are soluble, coloured, paramagnetic and heat resistant, having high flow temperatures. Their spectral characteristics and electro-physical properties have been investigated. The polytolane and polydiphenylbutadi-yne have the structure of substitute polyenes.
