The study on Characteristics of Surface-Active Polymer

Abstract:

Through the indoor comparative experiments, this paper studied the viscosity and surface tension of surface-active polymer, and calculated the critical micelle concentration, the surface adsorption capacity, molecular occupied area, and other parameters. Through comparing with intermediate molecular weight polymer, it is found out that surface-active polymer has characteristics of high viscosity and its viscosity is higher than common polymer under the same concentration. As a new type of polymer, surface-active polymer can reduce the tension and present a certain activity. The critical micelle concentration of surface-active polymer is 0.2532 g/L, the surface adsorption capacity is 1.678×10 -10mol.cm -2,and the molecule occupies an area of 0.9899 nm 2 .This theme also studied the emulsifying power and the characteristic of static and dynamic adsorption. The results show that the agents have approved emulsifying power with only 38% of the excluded water during 30 days. The static adsorption capacity of surface-active polymer is 1.92 mg/g. Under the same condition, its dynamic retention volume is greater than the amount of polymer retention.
