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.

CTS-9501161 Hatton MIT 本文主要研究了由中性、酸性和碱性嵌段组成的丙烯酸两性聚电解质的合成、表征和应用。 聚合物在高pH值下以单链形式分散，在中等pH值下形成稳定的胶束，并在等电点下沉淀。 选择的化学组成，结构和分子量的两性聚电解质将合成基于基团转移聚合。 这些聚合物的胶束化、增溶和吸附将在实验上和理论上作为盐和pH条件的函数来确定。 这些聚合物作为溶剂的应用，从工业排放的污染物去除，地下水修复和离子交换置换色谱将进行评估。 该研究可能会开发出可应用于环境和生物分离的新型共聚物。
