The acid hydrolysis method is usually utilized to separate acrylic polymer chains grafted onto amylopectin (AMP). The hydrolysis with the HCl acid has been found to be appropriate when we grafted hydroxyethyl methacrylate (HEMA) and hydroxypropyl methacrylate (HPMA). Using the perchloric acid method, various secondary reactions appear falsifying the grafting yields. © 1993 John Wiley & Sons, Inc.
