Professor Sandra Greer is supported by a grant from the Experimental Physical Chemistry Program to study the density, heat capacity and phase equilibria of polymerizing liquids; she will also be testing a number of theoretical models that may be applicable to them. This work will help us to understand how and why polymerization occurs ultimately allowing us to design and produce better plastics, synthetic oils and clothing materials. Greer is pursuing a two pronged attack to find out firstly, if certain theoretical models that have been proposed do in fact correctly predict the behavior of reversible polymerization. These systems often refered to as "living polymers" because the polymer-monomer equilbrium can be reversibly shifted by temperature changes; thus, mimicking chemical equilbrium behavior. Secondly, Greer will examine the concept of Wheeler et al. that the static properties (density and heat capacity) can, in fact, be treated as critical phenomena. Moreover, Greer hopes to see whether or not the theories used to predict and describe phase transitions in magnets can also be used to describe her "living polymer" systems' reversible equilibria properties.

桑德拉·格里尔教授得到了 实验物理化学计划，研究密度， 聚合液体的热容和相平衡 还将测试一些理论模型， 适用于他们。这项工作将帮助我们了解 以及为什么聚合最终会发生， 生产更好的塑料、合成油和服装 材料. 格里尔正在进行双管齐下的攻击，首先要找出，如果 已经提出的某些理论模型实际上 正确预测可逆聚合的行为。 这些系统通常被称为“活性聚合物”，因为 聚合物-单体平衡可以通过以下方式可逆地移动： 温度变化;因此，模仿化学平衡 行为其次，格里尔将考察惠勒的概念 等，静态性能（密度和热容） 事实上，可以被视为临界现象。此外，Greer 希望看看用于预测和 描述磁体中的相变也可用于 描述了她的“活性聚合物”系统的可逆平衡， 特性.
