Abstract

A model drug acetaminophen was mixed with PEO, and the morphology, nucleation numbers, and crystallization kinetics of PEO were altered accordingly. The spherulitic growth rate and isothermal DSC endotherm were analyzed by Hoffman-Lauritzen theory and Avrami theory, respectively. It was found that the fold surface free energy increased significantly with increasing drug content, indicating the chain folding of PEO became much more difficult in the presence of the small molecule drug.
