Summary Multiple crystallization elution fractionation (m‐CEF) is a new approach for operating CEF using multiple cooling/heating cycles to enhance physical separation of polymers with different chain crystallizabilities. In this work, an m‐CEF model was developed based on the concept of population balance with crystallization and dissolution kinetics. The model was found to describe the previously reported trend of experimental m‐CEF profiles well. Effect of m‐CEF operating cycles and column length was also examined.
