抄録

Trans-4 Polybutadiene has been fractionated by the succesive fractional precipitation method using the dilute solution of benzene with methanol as precipitant. The fractions were examined both osmotically and viscometrically in toluene solutions at 30°C.<br>The intrinsic viscosity-molecular weight relationship has been obtained as [η]=2.9×10-4Mn0.753. The molecular weight distribution curve has been obtained and compared with the curve of Cis-4 Poly-butadiene.<br>The second virial coefficient A2 have been calculated from the osmotic pressure′ data and thier molecular weight dependence were found as<br>Trans-4 Polybutadiene A2∝Mn-0.1<br>Cis-4 Polybutadiene A2∝Mn-0.2<br>in this experiment.
