Professor Sandra Greer of the University of Maryland is funded by the Theoretical and Computational Chemistry Program to perform experimental measurements of the phase behaviors of polymers in solution. Many of the proposed measurements will generate data that can be used to definitively test recent theoretical proposals of liquid-liquid phase separation in polymer systems. Methods include magnetic densimetry, rheometry, tensiometry and small angle neutron scattering. The polyethylene oxide polymer systems to be investigated have important applications in a broad range of industries, and the characterization of PEO/solvent phases should be of direct interest in many of these areas.

马里兰大学的桑德拉·格里尔教授由理论和计算化学计划资助，对聚合物在溶液中的相行为进行实验测量。许多拟议的测量将产生数据，这些数据可用于明确测试最近提出的聚合物体系液-液相分离的理论建议。方法包括磁密度法、流变法、张力法和小角中子散射法。将要研究的聚氧化乙烯聚合物体系在广泛的工业中具有重要的应用，而PEO/溶剂相的表征在许多这些领域中应该是直接感兴趣的。
