Abstract

1. The kinetics of the polymerization of phenylacetylene and 2-methyl-5-ethynylpyridine was studied, and the rate constants of the thermal polymerization and observed activation energies were determined. 2. On the basis of an analysis of the products of thermolysis and ozonization of polyphenylacetylene it was shown that the chain of polymer is constructed chiefly according to the "head-to-tail" principle. 3. A biradical mechanism of the initiation of the thermal polymerization of phenylacetylene was proposed.
