Solubility Behaviour of Cellulose Acetate Butyrate in Mixture of Solvents
Keyword(s):
In order to identify the proper solvent mixture for future processing from solution of cellulose derivatives, the laser light scattering method was used. The multiangle laser light scattering parameters of macromolecular chains in solution (weight-average molecular weigh , radius of gyration Rg and second virial coefficient A2) were correlated with the values of dielectric constant of solvent mixture (2-methoxyethanol + N,N-dimethylformamide). The experimental results revealed that the protic solvent favored the extended conformation of the macromolecules in solution, necessary condition to obtaine nanofibers by electrospinning.
