Abstract In‐situ polycondensation of terephthaloyl chloride and p‐phenylenediamine was carried out by solution or interfacial polycondensation methods in the presence of rubbers such as styrene‐butadiene triblock copolymers and acrylonitrile‐butadiene random copolymers so that a novel composite polymer of rubbers and poly(p‐phenylenetere‐phthalamide) was obtained. Mechanical properties of rubbers were greatly improved by the incorporation of rigid rod‐like polymers. In‐situ polymerization of N‐carboxy methyl‐L‐glutamate was carried out in solutions of rubbers so that a composite polymer of rubbers and poly(L‐glutamate) was obtained. Mechanical properties of rubbers were also greatly improved by the in‐situ polymerization, while solution blending of poly(L‐glutamate) did not result in the improvement of mechanical properties.
