Daily-used hydroxypropyl methylcellulose is a synthetic polymer mainly made from natural cellulose and then subjected to a series of chemical modifications. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from that of synthetic polymer. Its most basic raw material is cellulose, a natural polymer compound. Because of the particularity of natural cellulose structure, cellulose itself has no ability to react with etherifying agent. However, after the treatment of swelling agent, when the strong hydrogen bonds between molecular chains and chains are destroyed, the activity of hydroxyl groups will be released and become alkali cellulose with reactive ability. After the reaction of etherifying agent, OH groups will be converted into OR groups, thus obtaining cellulose ether.
