The primary structure of HEC is characterized by the substitution of hydroxyl (–OH) groups on the cellulose backbone with hydroxyethyl groups. The process involves treating cellulose with ethylene oxide, resulting in cellulose molecules that contain hydroxyethyl substituents. This modification not only enhances the solubility of cellulose in water but also contributes to the improved stability and functionality of the polymer.
