Equipment for a Polymer Laboratory

威廉和玛丽的聚合物实验室包括三个聚合物合成实验，四个涉及聚合物的溶液表征，两个处理本体聚合物的机械和热性能。该实验室的目标是让学生亲身体验重要的技术，并为他们提供聚合物化学原理的第一手经验。在这个项目中使用了两个主要的仪器。首先，用膜渗透计测定聚合物样品的数均相对分子质量，用光散射光度计测定重均相对分子质量，并测定分子大小。后者也将用于GPC仪器的下游，用于分析分子量分布。这一实验室课程的引入使化学系能够向其专业提供以聚合物为重点的化学专业的课程选择。该机构正在将奖金与等额的资金相匹配。

The polymer laboratory at William and Mary consists of three experiments in polymer synthesis, four involving solution characterization of polymers, and two treating mechanical and thermal properties of bulk polymers. The objective of the laboratory is to give students hands-n experience with important techniques and to provide them with first-hand experience in the principles of polymer chemistry. Two major instruments are utilized in this project. First , a membrane osmometer for determining the number-average molecular weight of a polymer sample and a light-scattering photometer for the weight-average molecular weight and also for determining molecular sizes. The latter will also be used downstream from a GPC instrument for the analysis of molecular-weight distributions. The introduction of this laboratory courses allows the Department of Chemistry to make available to its majors a curriculum option of a chemistry major with a polymer emphasis. The institution is matching the award with an equal amount of funds.
