ABSTRACT:
The present invention is a process for forming hydroxy-terminated aromatic oligomeric phosphates by the initial reaction of a monoaryl dihalophosphate, such as monophenyl dichlorophosphate, with an aromatic diol, such as resorcinol, to form a halo-terminated aromatic oligomeric phosphate and the subsequent reaction of that halo-terminated phosphate with aromatic diol to form the hydroxy-terminated aromatic oligomeric phosphate. The initial and subsequent reactions preferably employ a Lewis acid catalyst, such as magnesium dichloride.
