Polymer complexes of arylacetylenes with iodine

The exothermal reaction of phenylacetylene with p-diethinylbenzene and iodine at 100–130°C, which results in the formation of polymer complexes, is shown to be related to the dehalopolycondensation of the products of addition of iodine to arylacetylenes formed during the initial stages of the process. The structure and some physicochemical properties of the polymer complexes are studied.
