Abstract
The radiation crosslinking of polyethylene, polymethylsiloxane and other polymers was studied. The studies on the mechanism of crosslinking of polyethylene indicate that the crosslinking process takes place mainly as a result of the simultaneous detachment of two hydrogen atoms in neighboring molecules as a result of single primary event. The study of the irradiated polymethylsiloxane has shown that the part of the polymer which crystallizes at -40-50C DECREASES IN PROPORTION TO THE RADIATION DOSE. A comparative study of the process of radiation vulcanization of natural and synthetic rubber was made. It was shown that certain additives retard radiation vulcanization, while others accelerate it somewhat. (Author, modified-PL)
