Solubility and polymer‐solvent interaction parameters of 1,2‐polybutadiene

The dilute solution behavior of 1,2-polybutadiene newly developed was not anomalous within the range of crystallinity up to 25%. Therefore, the solubility and polymer-solvent interaction parameters could be determined by means of usual measurements of dilute polymer solutions. The former has been estimated from viscosity measurement proposed by Mangaraj. The latter was determined using the second virial coefficient obtained from osmotic pressure and light-scattering measurements.
