Polymerization of diphenyldiacetylene was effected in the presence of Ziegler type catalysts. The polymers, studied as obtained from the polymerization or after further reaction, are soluble products of relatively low molecular weight with interesting properties: very high thermal resistance, continuous absorption in ultraviolet and near visible regions, broad visible fluorescence spectra, semiconducting and catalytic properties.
