Copolymers were prepared by the condensation of rigid benzoyl-terminated poly@-benzamide) and flexible anilino-terminated poly(m-benzamide) prepolymers. The use of two monomers of the AB type and of end-capped prepolymers resulted in the formation of diblock molecules uncontaminated by triblock or m
## Abstract Anilinoβterminated poly(__m__βphenylene isophthalamide) [PhNH(MPDβI)] and benzoyl terminated poly(__p__βbenzamide) [PhCO(PBA)] were coupled according to a oneβpot twoβstep scheme of Yamazaki's reaction. Diblock copolymers with varying length of the flexible PhNH(MPDβI) segment, and simi
