| description | The invention relates to a method for purifying polymer material from polymer waste and the purified polymer material. Wherein the polymer material comprises at least one target polymer, at least one non-target polymer and at least one impurity. The method comprises the steps of: providing the plastic waste in solid form; dissolving the polymer material; optionally carrying out a first liquid-solid separation step; optionally adding at least one additive; precipitating the at least one impurity and the at least one non-target polymer from the solution; optionally adding at least one additive; separating the precipitate; optionally adding at least one additive and separating the at least one additive and the adsorbed remaining impurities; the residual solvent is removed and the purified target polymer material is optionally degassed. The invention also relates to a recovery obtainable by said method.
