抄録

Cis-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]=3.39×10-4Mn0.688. It was found that the molecular weight distribution curve obtained by the succesive fractional precipitation method were good agreement with the result obtained by the Spencer-Matumoto′method. Two samples which have difference Mooney viscosities were examined their molecular wieght distribution curves by the Spencer-Matumoto′method. Mooney viscosities seemed to depend upon the weight average molecular weight in this experiment.
