A high molar mass polycation poly(methacryloylethyl trimethylammonium methylsulphate), PMETMMS, dissolved in mixtures of water and acetone, was studied using light scattering during the reversible coil-to-globule transition. When the mass fraction of acetone in the solvent mixture, ␥, is higher than

Samples of a polyelectrolyte poly(methacryloylethyl trimethylammonium methylsulfate), PMETMMS, with molar masses M w Å 22-25 1 10 6 were examined with viscosity, static light scattering, and conductivity measurements in a wateracetone solvent. Because acetone is a nonsolvent for this polymer the mea
The structure of water absorbed in polyHEMA is studied by X-ray diffraction in the vitreous state at 77 K as well as in the liquid state at room temperature. Molecular packing at the level of the first neighbors IS found similar to that in bulk water but a distortion is observed at the level of the
