The effect of micro and macro mixing in continuous polymer reactor systems on long chain branching frequency and structure

本研究项目旨在开发一种预测聚合物分子中长链支化结构和频率的数学模拟方法。聚合材料通常在搅拌槽反应器容器中制成，然后通过熔化和成型加工成最终产品。这些产品的例子包括管子、瓶子、计算机机箱、薄膜和粘合剂。聚合物材料的加工性能取决于聚合物的流变性，而流变性又取决于聚合物链的分子特性(如组成、分子量分布、长链支化类型、频率和长度)。这些分子性质由初始反应容器中的条件决定。

This research project aims at developing a mathematical simulation method for predicting long chain branching structure and frequency in polymer molecules. Polymeric materials are typically made in stirred tank reactor vessels and then processed into final products by melting and shaping. Examples of these products include pipes, bottles, computer cases, films and adhesives. The processing properties of the polymeric materials depend on the rheology of the polymers which, in turn, depends on the molecular properties of the polymer chains (e.g. composition, molecular weight distribution, long chain branching type, frequency and length). These molecular properties are determined by conditions in the initial reaction vessel.
