Abstract
Przedmiotem zgłoszenia jest sposób oczyszczania roztworu polimeru od cieczy jonowej, który polega na tym, że roztwór od 70% do 98% masowych zawierający homopolimer metakrylanu N,N-dimetyloaminoetylu (DMAEMA), lub homopolimer metakryalnu hydroksyetylu (HEMA) lub kopolimery DMAEMA/HEMA o udziałach molowych FDMAEMA = 0,85, 0,75, 0,50, 0,25, 0,15 i średnim ciężarze cząsteczkowym od 12 200 g/mol do 32 400 g/mol i cieczy jonowej, korzystnie pochodnych cieczy jonowych 1,3-dialkoloimidazoliowych, rozpuszcza się w wodzie lub mieszaninach wodnych jako rozpuszczalniku i oczyszcza metodą elektrodializy przy początkowej gęstości prądu wynoszącej od 50 do 300 A/m2, korzystnie 100 A/m2,w której ciecz jonowa przenoszona jest z roztworu diluatu do roztworu koncentratu zawierającego początkowo tą samą ciecz jonową.The subject of the application is a method of purifying a polymer solution from an ionic liquid, which consists in the fact that the solution from 70% to 98% by weight contains N, N-dimethylaminoethyl methacrylate homopolymer (DMAEMA) or hydroxyethyl methacrylate homopolymer (HEMA) or DMAEMA / HEMA copolymers with molar fractions of FDMAEMA = 0.85, 0.75, 0.50, 0.25, 0.15 and average molecular weight from 12,200 g / mol to 32,400 g / mol of ionic liquid, preferably derivatives of ionic liquids 1.3 - dialkolimidazoliums, are dissolved in water or aqueous mixtures as a solvent and purified by electrodialysis at an initial current density of 50 to 300 A / m2, preferably 100 A / m2, in which the ionic liquid is transferred from the diluate solution to the concentrate solution initially containing the the ionic liquid itself.
