Novel Separation of Polymer Systems with High Throughput and Separation Performance Characteristics
The purpose of the invention at hand is a novel procedure for the separation of polymer systems with respect to molecular weight, chemical structure, chain architecture, and colloidal additives. At present, such separations are carried out by selective precipitation, fractionated crystallisation of the desired compound out of solutions or by gel chromatographic methods.
Fractionated crystallisation fails at amorphous polymers. Selective precipitation is inappropriate in cases of polymers with different structures and similar solubilities, and in cases of balanced chemical structures and different chain architectures, respectively. Gelchromatography only provides for a restricted throughput. The invention at hand pertains to separation procedure for polymer systems using permeation through polymer films ? semi-crystalline, cross-linked, amorphous ? with thicknesses in the scale of nanometers. Polymer films with thicknesses in the scale of nanometers provide for a high throughput of the polymers to be separated.
