Flow birefringence, intrinsic orientation and intrinsic viscosities of polyamidebenzimidazole (PABI) and poly-meta-phenylene-isophthalamide (PPIP) molecules have been studied for a wide range of molecular weights. The optical and conformational properties of PABI molecules in dimethyl acetamide (DMA
