A three‐step modeling approach to obtain rheological properties from the kinetics of the metallocene‐catalyzed homopolymerization of ethene is developed. With that, linear as well as slightly branched high‐density polyethylene is investigated. Therefore, a deterministic kinetic model of the metallocene‐catalyzed polymerization of ethene is set up and coupled with a Monte Carlo algorithm to obtain molecular weight distributions and polymeric microstructures. The topological information is used as input for the rheology model to compute linear and non‐linear rheological properties.

基于聚合动力学的HDPE流变特性建模

开发了一种三步建模方法,可从茂金属催化的乙烯均聚反应动力学获得流变性质。因此,研究了线性以及轻度支化的聚乙烯。因此,建立了茂金属催化的乙烯聚合反应的确定性动力学模型,并与蒙特卡罗算法相结合,获得了分子量分布和聚合物的微观结构。拓扑信息用作流变模型的输入,以计算线性和非线性流变特性。
