There is no significant variation found in thermal stability of binary and ternary blend for both A and C samples (Figure 6). Around 10%–18% residue left after thermal degradation at close to 650°C in all samples suggests the involvement of inorganic additives used during foam manufacturing....
Cellulose Acetate Butyrate (CAS 9004-36-8) information, including chemical properties, structure, melting point, boiling point, density, formula, molecular weight, uses, prices, suppliers, SDS and more, available at Chemicalbook.
Melting point depressionThe investigation of the miscibility between active pharmaceutical ingredients (API's) and polymeric excipients is of great interest for the formulation and development of amorphous solid dispersions, especially in the context of the prediction of the stability of these systems. ...
