Polymer properties, such as molecular weight and copolymer composition, are highly dependent on the process conditions under which they are made. The enhancement in understanding of the underlying concepts by undergraduate chemists and chemical engineers in the interdisciplinary field of polymer science is needed. This is to be accomplished by the coupling of reaction simulators with experimental design, reactor operation and process measurement. The equipment is specific for this purpose: 1) microcomputers for simulator development and studies; 2) computer controlled laboratory reactor for metering reactants and controlling, monitoring and recording reaction conditions; and 3) monomer/polymer monitoring equipment for determining conversion. Traditional polymer lab courses barely touch on the decision making processes behind the synthesis of various polymers and then only in a qualitative manner. In addition, the importance of monitoring and controlling the process is typically overshadowed by the need to measure the polymer properties. These are highly interdependent and of equal importance. An undergraduate's experience in both areas is necessary particularly with the increasing importance placed on communication between the bench chemist and the plant engineer.

聚合物的性能，如分子量和共聚物组成，在很大程度上取决于制造它们的工艺条件。在聚合物科学的跨学科领域，本科生化学家和化学工程师需要加强对基本概念的理解。这将通过将反应模拟器与实验设计、反应堆操作和过程测量相结合来实现。该设备是专门用于此目的的：1)用于模拟器开发和研究的微型计算机；2)用于计量反应物和控制、监测和记录反应条件的计算机控制的实验室反应器；以及3)用于确定转化率的单体/聚合物监测设备。传统的聚合物实验课程几乎不涉及各种聚合物合成背后的决策过程，而且只是定性的。此外，监测和控制过程的重要性通常被测量聚合物性能的需要所掩盖。这些是高度相互依存和同等重要的。本科生在这两个领域的经验是必要的，特别是在越来越重视实验室化学家和工厂工程师之间的沟通的情况下。
