1. As a result of the higher solubility arising from the introduction of methyl groups or an oxygen bridge into the p-polyphenylene part of the molecule of a diethynylarene it is possible to synthesize diacetylenes of this series containing a fairly large number of nuclei. 2. The syntheses and oxidative polycondensations of 11,24-diethynyl-12,23-dimethylbiphenyl, 11,44-diethynyl-12, 23,32,43-tetramethyl-p-quaterphenyl, and 4-ethynyl-4′-p-ethynylphenoxybiphenyl were carried out. The resulting polymers are partially soluble in benzene.
