Abstract
En fremgangsmåte for å fjerne forurensninger (inklusive løsningemiddel) fra en strammende polymer som i ett aspekt inkluderer oppløsning av et lite oppløselig strippemiddel i en strømmende polymer, hvor det lite oppløselige strippemiddel stripper forurensninger fra den strømmende polymer og danner en blanding av forurensninger og lite oppløselig strippemiddel, som unnviker fra den strømmende polymer, og blandingen separeres fra polymeren. I ett aspekt gjenvinnes resirkulerbart lite oppløselige strippemiddel og anvendes på nytt.
