Abstract
1. The kinetics of the polycondensation of chlorides of aromatic dicarboxylic acids with polycyclic bis-phenols, containing norbornane groups at the central carbon atom, were studied in ditolylmethane solution in the temperature interval 150–200°. 2. The reaction of terephthalyl chloride with 4,4′-(hexahydro-4,7-methylenindan-5-ylidine)diphenol is first order with respect to the bis-phenol and half order with respect to the acid chloride. 3. During the reaction, at high degrees of conversion in the interaction of other polycyclic bis-phenols with terephthalyl chloride, one and a half order of the reaction is preserved. 4. The mechanism of the formation of polyarylates of polycyclic bis-phenols differs from bimolecular. It is proposed that the reaction proceeds according to an ionic mechanism, and a kinetic scheme is proposed for the process. 5. The values of the effective rate constants at various temperatures and the parameters of the Arrhenius equation were determined.
