The Physical Chemistry of Living Polymer Solutions

在该项目中，马里兰大学帕克分校化学工程系物理化学项目的桑德拉·格里尔将继续研究聚合物相变的本质和平衡可逆聚合，即单体发生可逆化学反应形成聚合物。在这个项目中，将使用微观和宏观实验方法来研究临界点附近的能量变化、结构变化和接近平衡的细节。微观研究将使用中子散射来研究溶液的结构和聚合物在其中的运动。宏观研究将包括测量平衡性质，如密度、热容、相图、动力学速率常数和输送性质，如粘度。这些可逆聚合的研究对于理解具有技术和生物学意义的体系中聚合物的形成机制具有重要意义。

In this project in the Physical Chemistry Program of the Chemistry Division Sandra Greer of the Department of Chemical Engineering of the University of Maryland- College Park will continue her research on the nature of the phase transitions of polymers and equilibrium reversible polymerization, in which the monomers undergo a reversible chemical reaction to form polymers. In this project microscopic and macroscopic experimental methods will be used to study the energy changes, the structural changes, and the details of the approach to equilibrium near the critical point. The microscopic studies will use neutron scattering to investigate the structure of the solutions and the motion of the polymers in them. The macroscopic studies will include measurements of equilibrium properties such as density, heat capacity, phase diagrams, kinetic rate constants and transport properties such as viscosity. These studies in reversible polymerization are of relevance for understanding the mechanism of polymer formation in systems of technological and biological interest.
