Radiation cross-linking of elastomers in the presence of chlorine-containing and chroman compounds
- and others
The role of hexachloro-p-xylene (HCPX) and 6-hydroxy-2,2,5, 7,8-pentamethylchroman (HPMC) in butadiene-nitrile rubbers (SKN) in the systems SKN-40+HCPX+ZnO and SKN- 40+HPMC+ZnO exposed to radiation was investigated. A change in the molecular structure of the SKN-40 rubber in the presence of HCPX and HPMC after irradiation with a dose of 150 kGy of {gamma}rays was demonstrated by physicochemical and spectral methods. The cross-linking yields and appearance of cross-links in the elastomers were determined for each system studied as a function of the absorbed dose. A hypothesis was advanced concerning the mechanism of radiation-heterogeneous conversion of elastomers in the presence of HCPX. 17 refs., 3 figs., 1 tab.
