FIELD: organic chemistry, in particular blocked mercaptosilane cross-linking agents.
SUBSTANCE: claimed blocked cross-linking agent is obtained by reaction of 3-chloropropyltriethoxysilane and sodium 2-mercaptobenzothiazolate in isopropyl alcohol solution at 80-82°C. Mixture is agitated at this temperature for 15-20 h, cooled and alcohol is distilled followed by separation of finished product from sodium chloride. Cross-linking agent of present invention is useful in rubber mixtures based on non-polar polydienes with silicic acid and mineral fillers to simplify dispersion thereof in mixtures.
EFFECT: rubbers with decreased hysteresis.
