SUPERMOLECULAR STRUCTURE OF THE BLENDS WE AKLY CHARGED POLYMERS IN AQUEOUS-SOLUTION

Supermolecular structure of the blends of weakly charged polymers in a queous solution was examined using the system poly(acrylamide-co-vinyl sulfonic acid)-poly(1-vinyl-1,2,4-triazole)-water as an example. Phase diagram of this ternary system was deduced. Separation of the system into two macroscopic phases was found to be accompanied by the formati on of microdomain structures in one or in both phases, depending on th e initial concentrations of components. Dimensions of supermolecular a ssociates were calculated from turbidity spectra. Experimentally deter mined radius of supermolecular particles (0.1 mm) lay within the range theoretically predicted for microdomains in blends of weakly charged polyelectrolytes.
