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

点击翻译按钮获取中文摘要

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.
