Chemical recycling of polystyrene (ps)waste is of crucial importance to the environment. In according to the importance of utilization of anion resins in reducing water hardness,it'simportant to produce high performance resins by using cheap methods in industry. One of the important points for having an anion resin with high ion exchange capacity is width bond controlling, number of acid sites and the situation of sulfunate groups. This study is important in according to the utilization of resins in water purification industry. Also in this study we have used the FT-IR,NMR,DTG,TG methods for data analyzing.
