### Abstract

A study was made of the thermal, peroxide, and radiation vulcanization of modified butadiene-acrylonitrile rubber SKN-40PVKh-30 in the presence of a polyhalomethyl compound, 1,4-bis[(4-trichloromethylphenyl)dichloromethyl]benzene, with epoxy and phenol-formaldehyde resins and 4,4′-dithiobis-N-phenylmaleimide (a sensitizer) additionally included in the formulation with the aim to improve the technical properties of the vulcanizates and elastomeric materials. The parameters of the three-dimensional network of the vulcanizates were studied by sol-gel analysis; the total number of active chains of the network (1/M c), number of cross-linked molecules $$(1/M_{n_\tau } )$$ , and gel fraction content were determined for the thermal, peroxide, radiation, and thermoradiation vulcanizates.
