Molecular weight distribution has been investigated for polycaproamide obtained in lowtemperature, anionic polymerization of caprolactam in the presence of the sodium salt of caprolactam and carbon dioxide in solvent; fractionation has been performed at 25 Β° using phenol-tetrachloroethane as solvent
Polymerization of styrene to high degrees of conversion (up to 99.8%) was carried out. The obtained polystyrene was fractionated by distribution between two liquid phases and also by fractionating precipitation. Molecular weights of the fractions were determined and the molecular weight distribution
