Construction and Building Materials
The structure of hydroxyethyl cellulose is derived from cellulose, a naturally occurring polymer made of glucose units linked by β-1,4-glycosidic bonds. In HEC, some of the hydroxyl groups in the cellulose backbone are replaced with hydroxyethyl groups through a chemical modification process called etherification. This substitution occurs randomly across the cellulose chain, leading to varying degrees of substitution (DS), which significantly influences the solubility and viscosity of HEC in aqueous solutions.
