Studies on the melt viscosity and physico-chemical properties of cellulose acetate propionate composites with lactic acid blends

Cellulose acetate has a high melting temperature due to intense intermolecular hydrogen bonding and is not significantly different from the deterioration temperature, so decomposition may occur during processing. Generally, in order to prevent pyrolysis of CA in the melting process, it is dissolved by using a solvent such as CS2 or H2SO4. However, it is not suitable for extrusion and injection process, and plasticized CA composition is prepared...
