Efficiency of polymer fractionation—A review

Abstract: With respect to molecular masses, polymers are polydispersive. Since many of their properties depend on the distribution of molecular masses, to study this correlation it is necessary to have samples of narrow molecular mass distribution or samples with accurately defined distribution. In spite of the developmental progress of fast instrumental methods (analytical and preparative gel chromatography) used to determine the molecular mass distribution curve and to obtain higher amounts of fractions of narrow mole… Show more

“…Molecular weight and PDI show a great influence on the fractional precipitation behavior. 59 Solubility difference between high-and low-molecular weight polymers in solutions is the driving force for fractional precipitation. If the difference in molecular weight in the polydisperse polymer system is larger, the fractional precipitation would be more significant.…”
