How a strong non polar molecule/polymer with having single or two amine/hydroxyl ions can be neutralised? Can it be done any desirable organic solvent with conc HCl? I had tried with water but unfortunately no results!
May be it will be useful for you to read about anionite neutralisation. Standart industrial laboratory procedure of determining dynamic and static capacity of anionites (polysterene polymer with a lot of CH2N(CH3)2 or other amino groupes consists in rather long time washing (titration) of polymer in a burete by HCl solutions
