Objective To study the hemostasis activity of iodine complex with carboxymethyl chitosan .Methods The polymers were prepared with azodiisobutyronitrile as the initiating agent and sodium acrylate ,N‐vinylpyrrolidone ,carboxym‐ethyl chitosan and N ,N′‐methylene diacrylamide as the raw materials .It was then complexed with iodine to generate iodine complex with carboxymethyl chitosan ,and the hemostasis activity was tested at the same time .Results The polymers could absorb water with the value of 103g/g and showed potent hemostasis activity for auricular veins and femoral veins .Conclusion The results showed that hemostatic effect of polymers was better than that of hemostatic sponge and Quikclot .
