Abstract

PURPOSE: To obtain a straight-chain polybenzyl by polycondensation of a hagenated benzyl in the presence of an iron oxide prepared through thermal decomposition of ferrous sulfate as a catalyst.
CONSTITUTION: An ferric oxide prepared by thermal decomposition of ferrous or ferric sulfide is used as a catalyst in polycondensation of a halogenated benzyl. In the preparation of the catalyst, ferrous sulfate is heated in an atmosphere of air or nitrogen under a reduced or an atmospheric pressure at 250W750°C for 30 minutesW4 hours; ferric sulfate, at 550W750°C, and thermally decomposed into ferric oxide which is used as the catalyst to give a straight-chain polybenzyl free from branches. The catalyst has specificity. Ferric oxide prepared by heating ferric hydroxide has no effect, ferric oxide from nickel or cobalt sulfate which is a homologue compound of iron is inert.
