METHOD OF SEPARATING POLYMERS FROM REGENERATED PRODUCT AND CLEANING THEREOF Russian patent published in 2020 - IPC C08J11/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of separating polymers from regenerated product (rP) and cleaning thereof. rP is brought into contact at high temperature and pressure with an extracting solvent to obtain extracted rP (erP). Solvent under conditions sufficient for dissolution of the first polymer is brought into contact with erP to obtain a solution which is purified at high temperature and pressure by bringing it into contact with solid medium to produce purified solution of first polymer. Purified polymer is then separated from the purified solution, and the method steps are repeated until all polymers are separated and cleaned.

EFFECT: disclosed is a method of separating polymers from a regenerated product.
