Anion-exchange group was introduced into the polymer chains graft onto a Low-Density Polyethylene (LDPE) by radiation-induced graft polymerization. A synthesis of anion-exchange membrane to use Vinyl Benzyl Trimethyl Ammonium Chloride (VBTAC) and Hydroxyethyl methacrylate (HEMA). Subsequently, Investigated permeation characteristics of VBTAC/HEMA membrane. The VBTAC/HEMA membrane was selected because of its practical physical strength. Anion-exchange membrane with degree of VBTAC/HEMA grafting higher than 96% to reaction time 6t.
