Summary: | Photochemical oxidation of BR polydimethylsiloxane rubber during irradiation by the full light of DRT-1000 lamp over atmospheric oxygen was studied by the methods of Fourier Transform Infrared Spectroscopy and chemical treatment. The studies found that in these conditions crosslinking reaction of polymer with formation of intermolecular dimethylene bonds are observed, accompanied by their subsequent oxidation and formation of relatively stable carbonyl and carboxyl polymeric compounds. |
