<p>It is described a process for separation of multicomponent synthetic polymers with a barrier process. As mobile phase is used a mixture of strong and weak solvent in the composition of 70/30 h./Wt. dimethylformamide / toluene, wherein barriers apply at the sample of mixture of macromolecules, at first with a higher concentration of the weak solvent and later with barrier of the weak solvent alone.</p> |
