Abstract
A set of statistical vinyl chloride–vinyl acetate copolymers of various vinyl acetate content was prepared. The samples were fractionated by preparative gel permeation chromatography (GPC), and the fractions were characterized by analytical GPC, light scattering, and viscometry. The original samples were characterized also by osmometry and chemical analysis. The molecular parameters calculated from GPC analysis using the universal calibration were correlated with those of light scattering measurements and viscometry. It was found that in the range of chemical compositions and molecular weights studied, the chemical composition does not significantly influence the results of GPC analysis.
