Abstract
For [NCO]/[OH]>1 ratios, a second transition at 70 °C was observed and attributed to hard segment interactions. Using swelling measurements, the solubility parameter δ, polyurethane-THF interaction parameter (Ï), crosslink densities (νe) and the molecular weight between crosslinks (M¯c) were determined.
