Intrinsic viscosity measurements were carried out on dextran samples (of different molecular weights) in aqueous solutions at 25, 28, 31, 34, 37, 40, and 43ยฐC. The extrapolation methods were used for the data; they gave unperturbed dimensions, K 0 , of the chain. The unperturbed root-mean-square end

Studies were performed to examine the effect of ionic salts on phase transitions, dissolution rates, and diffusion coefยฎcients of water in gels of poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) with polymer concentrations ranging from 22 to 32% w/w and salt concentrations rangin
