Acrylic Polyampholytes for Environmental and Biological Separations

本文将研究由中性、酸性和碱性块组成的丙烯酸多两性聚合物的合成、表征和应用。聚合物在高pH下以单链形式分散，在中等pH下形成稳定的胶束，在等电点析出。选择化学组成、结构和分子量的多两性聚合物将基于基团转移聚合合成。这些聚合物的胶束作用、增溶作用和吸附作用将作为盐和pH条件的函数在实验和理论上进行测定。将评价这些聚合物作为溶剂在工业排放污染物去除、地下水修复和离子交换置换色谱中的应用。该研究可能会导致在环境和生物分离中应用的新型共聚物的开发。

CTS-9501161 Hatton MIT The synthesis, characterization and applications of acrylic polyampholytes consisting of neutral, acidic and basic blocks will be studied. The polymers disperse as single chains at high pH, form stable micelles at intermediate pH and precipitate at the isoelectric point. Polyampholytes of selected chemical composition, architecture and molecular weights will be synthesized based on group transfer polymerization. The micellization, solubilization and adsorption of these polymers will be determination experimentally and theoretically as a function of salt and pH conditions. The applications of these polymers as solvents for contaminant removal from industrial discharges, for groundwater remediation and in ion-exchange displacement chromatography will be evaluated. The research may lead to the development of new copolymers with applications in environmental and biological separations.
