✦ Synopsis

Phase-separation temperatures have been measured for polyacrylic acid dissolved m aqueous sodium chloride solutions over a range of ionic strengths, degrees of neutralisation, polymer concentrations and molecular weights. The data are used to derive 0-temperatures for this system. The dependence of the 0-points on ionic strength and degree of ionisation is discussed and the results are briefly compared with data for other polyelectrolytes.
