A method for separating polymers from a physically commingled solid mixture containing a plurality of polymers comprises dissolving a first one of the polymers in a solvent at a first lower temperature to form a first preferably single phase solution and a remaining solid component. The solid component contains additional polymers which are not soluble to the solvent at the first temperature but which may be soluble at higher temperatures. The method includes subsequently heating the solvent to dissolve additional polymer from the solid component to form...
A method for separating polymers from a physically commingled solid mixture containing at least three polymers, which includes at least two different polymers which are members of the PE family, by selective dissolution, comprising: dissolving at least one first polymer of the mixture in a selected solvent at a first temperature to form a first solution and a first remaining solid component which contains at least two polymers of the mixture which are insoluble in the selected solvent at the first temperature but soluble in the selected solvent at higher...
