MISCIBILITY OF CHITOSANS POLYAMIDE-6 BLENDS

Chitosans with different degrees of deacetylation were prepared by a c hemical method, and miscibility between chitosan and polyamide 6 was e xamined as a function of the degree of deacetylation in chitosan. From dynamic mechanical analysis and solution viscosity measurement, it ma y be concluded that there are specific interactions between amorphous regions of both polymers and that the miscibility of the blends become s better as the degree of deacetylation in chitosan decreases.
