摘要：

Osmotic pressure data, obtained from a study of four block copolymers, have been used to calculate second virial coefficients and number average molecular weights. The virial coefficients were determined over a range of temperatures in toluene and cyclohexane. The theta temperatures, entropy of dilution, heat of dilution and the solvent-solute interaction parameters were derived and their behaviour is discussed. © 1969.
