Cellulose acetate buyrate has a unique structure. It is an organic compound obtained by esterification of cellulose with acetic acid and butyric acid.

In this structure, some hydroxyl groups on the basic skeleton of cellulose are replaced by acetyl and butyryl groups. Acetyl groups give the material a certain luster and hardness, while butyryl groups enhance its flexibility and weather resistance. Its molecular chains have specific arrangements and spatial configurations, which affect the physical and chemical properties of materials.

From a microscopic perspective, this structure results in different intermolecular forces, which are related to its solubility and melting characteristics. In practical applications, this unique structure makes cellulose acetate butyrate widely used in plastics, coatings and other fields to meet various performance requirements.
