The project was conducted at Ecole Nationale Superieure des Industries Chimiques in conjunction with Worcester Polytechnic Institute. The objective was to investigate the aqueous medium behavior and surface-active properties of native dextran and its derivatives. Experimental variables such as concentration, modification process, chemical structure, and time were examined. Optimization techniques such as obtaining detectable effect of polymeric surfactant by extending the holding time, running a warm water circulation, and the use of drying oven were applied to improve the accuracy of the tests. Different modification process of the polymeric surfactant led to the different surface-active properties. Recommendations were made for the future work continuing the project.
