Abstract
Thermal analysis of samples of chitosan–poly(methyl acrylate) block copolymer after exposure to electromagnetic fields, ultraviolet radiation, ultrasound, and biodestructive agents is performed for the first time by means of differential scanning calorimetry in the range of 250–510 K and thermogravimetry in the region of 300–850 K. It is shown that the combined effect of physical factors and biodestructive agents alters certain physicochemical properties: the temperatures of physical transformations, the temperatures of the onset of thermal degradation, and the nature of thermal decomposition.
