- During this reaction, the hydroxyl groups on the cellulose molecules are partially substituted with methyl and hydroxypropyl groups, resulting in the formation of HPMC. The degree of substitution determines the physical and chemical properties of the final product, such as its viscosity, gelling ability, and solubility.
