The polymerization of phenylacetylene to polyphenylacetylene was accomplished with the combined catalysts triethyl aluminum and titanium tetraethoxide. The progress of the reaction was monitored by gas chromatography. The parameters included temperature (−80, 25, 140°C), solvent (benzene, chlorobenzene, toluene, cyclohexane, and nitrobenzene), mole ratio of catalysts (Al/Ti; 1.5, 3.0, 4.5, 6.0, and 9.0), aging times of catalysts (2, 10, and 40 min), and order of addition of reagents. Derivatives of polyphenylacetylene were obtained by the acylation of polyphenylacetylene with p‐nitrobenzoyl chloride, the sulfonation of polyphenylacetylene with benzenesulfonyl chloride, and the formation of polyphenylacetylene complexes with complexing agents such as bromine, iodine, iodine chloride, boron trifluoride, and ferric chloride. A new phenylacetylene‐acetylene product mixture was produced by the polymerization of phenylacetylene and acetylene at 25 and −80°C. The electrical conductivity of polyphenylacetylene and its derivatives is in the range of 10−10−10−3 Ω−1 cm−1.

Relatively high electroosmotic pressures are produced when a dissociable species such as water is present in the system 7-alumina-2-propanol and potentials in the kilovolt region are applied. Pressures above 3 atm were observed in this study. A theoretical expression, based on Onsager's treatment of the dissociation field effect, is derived for the electroosmotic pressure as a function of the applied potential. The equation agrees qualitatively with the measured data.
