摘要：
The deformational-strength characteristics of chitosan films with different molecular weight and the degree of deacetylation derived from water-acid solutions with different nature and concentration have been researched. The comparison of the strength properties of films formed on different base was carried out. It showed, that the change of acid hydrocarbonic residual length in the composition of the solvent allows to regulate the bursting strength (rupture resistance) and resilience (elastic) modulus of the film at wide range.
