Hi, I am trying to graft maleimide to a polysaccharide, but I am having troubles in dissolving my polymer after the grafting to the carboxylic groups. Any tips could be useful.
Yes, it does. The solubility of any polymer is reduced when it is grafted. This occurs because once grafted, the polymer chains can not flow themselves due to the solvent action. The polymer will swell, but not solubilize.
