Flow birefringence (FB) in solutions has been investigated for a number of samples of polyamide-hydrazide (PPAH) in dimethylsulphoxide; intrinsic viscosities [r/] of the same solutions have been measured. Characteristic values of FB, It/I, and orientation angles [z/g] of the solutions were determine

Light-scattering measurements have been carried out Ior 18 samples of polyamide hydrazide (PAH} in dimethylsulphoxide (DMS) with an over 10-fold variation in molecular weights. It was shown that the excluded volume effect in DMS does not appreciably affect the size of PAH molecules. The length of th
