An anion exchange membrane was prepared by amination of chlorinated polypropylene (CPP) and ethylenediamine (EDA) at a low temperature and was investigated with respect to not only its physical properties but also its electrochemical properties. The degrees of amination were 46.05, 47.07, 50.56, and 56.58% at 30, 40, 50, and 55°, respectively. The CPP membrane had no water uptake, whereas, that of the CPP-EDA membrane was 0.153, 0.243, 0.309, and 0.410 g of H2O/g of dry membrane, respectively, with increasing amination. The CPP-EDA membranes possessed an ion exchange capacity in the range 0.557–1.498 mequiv/g of dry membrane and a fixed ion concentration in the range 4.198–5.114 mequiv/g of H2O. The ionic conductivity of the CPP-EDA membrane was highest when the water uptake was highest. Those of the CPP-EDA membrane were in the range 0.475 × 10−2–0.999 × 10−2 S/cm. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
