摘要：
High temperature thermal gradient interaction chromatography (HT-TGIC) have been developed to measure the chemical composition distribution (CCD) of ethylene/1-olefin copolymers over a wide range of compositions. Multiple high temperature thermal gradient interaction chromatography (m-HT-TGIC) is a concept developed to further enhance the physical separation of copolymer components by performing multiple adsorption/desorption cycles, similarly to the operation of multiple crystallization elution fractionation (m-CEF) developed earlier. In this work, a mathematical model for describing m-HT-TGIC is developed based on population balances in multiple non-equilibrium adsorption/desorption stages for ethylene/1-olefin copolymer blends. The effects of number of m-HT-TGIC cycles, section length, and column length are also reported and discussed.
