Bisphenylene orthocarbonate (Ⅱ) was synthesized by the reaction of dicopper catecholate with carbon tetrachloride
and underwent cationic ring-opening polymerization with the introduction of phenyl group into the main chain. The obtained polymer with ester and ether group was verified by IR and 1H NMR spectra. Based on the analysis of the polymer structures
the polymerization mechanism was proposed. Its Tm and Tg are 254℃ and 160℃ respectively. No decomposition of the polymer was observed below 320℃.The volume expansion property of the monomer during polymerization was studied by measuring the density difference between I and its polumer at various temperatures.
