The polycondensation of p‐aminobenzoic acid by the use of triphenylphospine and hexachloroethane is described. One way to obtain a mixed solution of rigid rod and flexible coil polymers is the polycondensation of the rigid chains in a solution of a flexible polymer matrix. Results on matrix polycondensation of poly(p‐benzamide) in solutions of poly(methyl methacrylate), poly(methyl methacrylate‐co‐styrene), polystyrene and polyacrylonitrile are reported. It is shown that there exists an interrelation between the phase behavior of the mixed polymer solutions and the influence of the matrix polymer on the synthesis of poly(1.4.‐benzamide). The ternary phase diagrams of the rigid rod/flexible coil polymer solutions were determined.
