FIG. 1.

Heating curves of pure Cl () and of a mixture -DEB + Cl ().

FIG. 2.

ESR spectra: radicals produced by the low-temperature action of chlorine on -DEB (1), -DEB γ-irradiated at 300 K (2), peroxide radical formed during oxygen admission to the system AA + Cl at 170 K (3). Spectra were recorded at 77 K.

FIG. 4.

Infrared spectra of the -DEB monomer (a) and its oligomers and polymers prepared by γ-irradiation (b) and low-temperature operation of molecular chlorine (c).

FIG. 5.

Infrared spectra of polyacrilamide obtained by γ-irradiation of AA (), by molecular chlorine action on AA (), and molecular chlorine action on AA solution in glycerol ().
