The paper is devoted to investigation of mechanochemical halide modification of siloxane rubber (SKTV) using chlorine and fluorine-containing modifiers. Rubber compounds based on modified and original unmodified, siloxane rubbers were prepared. Rheological and curing properties of obtained rubbers were examined. In the established time optimum vulcanizates were obtained and their physical, mechanical and some special properties were studied. In order to study the molecular mobility of the modified rubbers ESR-spectroscopy study was carried out. The analysis of molecular mobility of modified rubbers has shown previously unknown regularities of mechanochemical halide modification of siloxane rubber using chlorine and fluorine-containing modifiers. The rheological and curing properties of the initial and modified rubbers were investigated. The application fields of halogen modified rubbers was determined.
