摘要：
A poly (vinylchloride-diethyl maleate) copolymer has been fractionated by the repeated precipitation method. All fractions and the unfractionated sample have been characterized by viscometry, dynamic osmometry, Zimm static osmometry, light scattering and gel permeation chromatography. After correction for polydispersity, a left bracket eta right bracket approximately M relationship for monodisperse polymer solutions has been obtained. For the copolymer solution in THF, the second virial coefficient A//2 decreases as the molecular weight increases.
