Abstract
AbstractSome polymers and copolymers were precipitated from solutions by nonsolvent addition with and without stirring as well as by temperature lowering. It turned out that the precipitate is charged in all these cases. Stirring yields an increase of the charge quantity. The charging of the precipitate in experiments without stirring being a result of electron transfer between the solvent and polymer rich precipitate phase is probably due to the density fluctuations. The precipitation by stirring was used for preparative purposes to remove the precipitated drops from solution by fractionation. Deviation in composition observed in different fractions of copolymers could influence the molecular weight and molecular weight distribution measurements.
