Abstract
The chemical heterogeneity of polyphenylenes obtained by trimerization polycyclo-condensation of acetylaromatic compounds has been investiga ted by GLC-MS analysis of the products of trimerization cyclocondensat ion of acetophenone. The mechanism for the formation of side products of the reaction is discussed. The presence of dypnone fragments in the polyphenylene structure results in a decrease in the thermal stabilit y of these polymers.
