Abstract

Earlier (2) we reported the preparation of a number of heterocyclic intermediates suitable for the preparation of ordered copolymers containing heterocyclic rings. In this paper we wish to describe the method of synthesis and the properties of some benzoxazole and benzothiazole diamines and a benzoxazole diacid and its acid chloride derivative; these compounds are particularly suitable for the preparation of thermally stable ordered ...
