HPMC is synthesized from cellulose, a naturally occurring polymer made of β-D-glucose units linked by β(1→4) glycosidic bonds. The modification of cellulose to produce HPMC involves two key processes methylation and hydroxypropylation. Methyl groups (–OCH3) are introduced to the cellulose backbone, replacing some of the hydroxyl groups (–OH), while hydroxypropyl groups (–O-CH(CH3)2) are added to enhance solubility and functional properties. The resulting structure maintains the fibrous backbone of cellulose but introduces hydrophobic and hydrophilic characteristics that significantly affect its behavior in solution.
