Extrusion is a very important polymer processing operation. Conventional extrusion involves melting, homogenizing and shaping of polymeric materials into continuous final plastic products such as films and fibres. Reactive extrusion combines the previously mentioned operations with reaction(s) in the molten polymer for the purpose of producing new materials with enhanced properties. Typical applications involve reactive blending, addition of functional groups on otherwise inert polymers, and modification of molecular weight and structure. Each operation is governed by underlying interactions between material properties and processing conditions. The main thrust in the proposed research program is the fundamental understanding of these interactions in industrially important reactive and conventional polymer processing operations.

挤出是一种非常重要的聚合物加工操作。传统挤出包括将聚合物材料熔融、均化和成型成连续的最终塑料产品，如薄膜和纤维。反应挤出将前面提到的操作与熔融聚合物中的反应(S)相结合，目的是生产具有增强性能的新材料。典型的应用包括反应性混合，在其他惰性聚合物上添加官能团，以及改变分子量和结构。每个操作都受材料特性和加工条件之间的潜在相互作用的制约。拟议研究计划的主旨是对工业上重要的反应性和常规聚合物加工操作中的这些相互作用的基本理解。
