functional groups. It has improved weathering resistance and lower moisture absorption compared to cellulose acetate. The exact properties of a CAB compound is determined by the composition of butyrate vs acetate functional groups.

Simplified representation of cellulose acetate butyrate with acetyl (blue) and butyryl (green) groups highlighted. The distribution of these ester groups can vary within the polymer chain.

CAB is commonly used as a binder or additive in coatings. Another usage of CAB is the production of rigid gas-permeable contact lenses.
