Effects of Some Parameters Affecting Designing of Nano-Water Hydrophobically Associating Polymers in Aqueous Solution

摘要

A novel series of water-soluble hydrophobically associating terpolymer (WSHAT) nano particles with optimum thickening effect were successfully synthesized via free radical emulsion polymerization using ethyl acrylate (EA), methyl acrylic acid (MAA), polymerizable surfactant (AS-25 MA) and N-methylol acrylamide (NMA). The terpolymers were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), Size Exclusion Chromatography (SEC), Zeta-sizer and Zeta-potential. The results obtained from various characterizations revealed that the molecular segments in amorphous form with the particle sizes of 30-120 nm. The results showed that nano modified WSHAT have better thickening effect as compared with commercial samples and hence can be used as nano modified thickner.
