摘要
For determination of mol. wt of silicone rubber Lukopren G 1000 fractions the method of molecular mass determination by vapor-phase osmometry has been used and as solvent-precipiant system toluene-methanol chosen for fractionation. A distribution curve has been plotted for calculated mol. wt of individual fractions. Lukopren G 1000 proved to conform to Wesslau distribution.
