Abstract
New polyquinazoline polymers are provided by reacting novel monomers, The polymers incorporate repeat units that have at least one quinazoline nucleus and at least one ether linkage at the quniazoline 2 or 4 position. The quinazoline polymers are prepared by treating a monomer which comprises a quinazolone nucleus having one activated halide group with a base in a dipolar solvent to thereby form the polyquinazoline polymer.
