Two kinds of porous nylon-6 membranes containing or not containing carboxymethylcellulose (CMC) resins were prepared from a methanol solution of nylon-6 and calcium chloride. The sorption effects of calcium chloride on the thermal properties of these membranes were investigated by DSC, together with the observation of morphologies. From the DSC curves, it was revealed that calcium chloride disturbed the reorganization of nylon-6 crystals during the heating process. The mixing of CMC resins gave the porosities with specific shapes to the nyloxi-6/CMC-resin composites.
