Abstract
The molecuar weight distribution of polyvinyl chloride (PVC1) samples has been studied by the column fractionation. The molecular weight distribution function obtained by this method has been compared with the results of the fractional precipition and ultracentrifuge methods. It was found that this method gives the highestMw/Mn value. Thereliability of this method has been confirmed by the agreement between the observed value of intrinsic viscosity [η] and the value calculated from the molecular weight distribution obtained.
