Cellulose acetate (CA) has been used for microfiltration/ultrafiltration applications because of its good solubility in common solvents. However, it is sensitive to chemical and physical degradation. Therefore, in this study, cellulose acetate was crosslinked with terephthaloyl chloride (TPC) in dimethylacetamide (DMAc) solution to complement these weakness. Cross-linking was confirmed by increasing in dope solution viscosity and FT-IR. To indicate the chemical resistance, weight loss was observed after the cross-linked CA membranes were immersed in ethanol, hexane, acetone and DMAc solvent for 24h. The physical properties were evaluated by the tensile strength. In the result of experience, effect of the degree of cross-linking by increasing of the concentration of TPC improved the chemical and physical properties of CA.
