Abstract
The transition from the unentangled regime to the entangled one at higher concentration and the existence of hydrogen
bonding were analyzed by dynamic viscosity. In addition, morphological properties of cellulose acetate phthalate
(CAP) in solvent/non-solvent mixtures of 2-methoxyethanol/water were studied. The increase of water content
contributed significantly to hydrogen bonding with cellulose acetate phthalate, generating the entanglement process,
along with other types of interactions. Our research demonstrated that CAP easily dissociate in a relatively low polar
solvent, such as 2-methoxyethanol, leading to strong intermolecular interaction with the addition of water, ascertaining
the influence of hydrogen bonding on the thermodynamic properties. This study is significant for using cellulose
acetate phthalate in different domains.
