Abstract
AbstractIn order to prove that the carbonyl‐olefin exchange reaction (COER) is a step reaction, a shorttime experiment was carried out, from which only linear oligomers were obtained. The dimer was identified by comparison with an authentic sample. The polymer can also be obtained starting from the dimer. The polymer retains its reactivity. Treated with WCl6 alone or in the presence of the corresponding monomer it yields products of increased molecular weight. The reaction takes place even in the presence of its low‐molecular‐weight by‐product benzophenone. Treatment of the polymer with benzophenone and WCl6 leads to a molecular weight increase. These results prove that the COER proceeds as a non‐equilibrium polycondensation.
