The structure and properties of film materials obtained from solutions of nitrile-butadiene rubber and chlorinated polyisoprene taken at ratios of 100 : 0, 80 : 20, 50 : 50, 20 : 80, and 0 : 100 are examined. DSC, EPR, viscometry of dilute polymer solutions, FTIR spectrometry, and elastic-strength testing are applied. Methyl acetate, ethyl acetate, butyl acetate, acetone, and methyl ethyl ketone are used as solvents. It is shown that the introduction of up to 50 wt % chlorinated polyisoprene in the polymer blend weakly affects the glass-transition temperature, elastic modulus, degree of ozone oxidation, and molecular mobility, whereas a higher concentration of chlorinated polyisoprene provides marked changes in these parameters. The thermodynamic quality of the solvent determines the structural and dynamic parameters of the studied film materials.
