; ;
The results are given of an investigation of the tetrahydrofuran-soluble fraction of hard-coal pitch by gel permeation chromatography on Sephadex LH-20. It has been shown that batches of pitch from one factory supplied previously in correspondence to the GOST do not preserve constancy of the molecular mass distribution. A correlation has been established between the molecular mass composition and the viscosity of the pitch.
