he conventional two-component condensation -type RTV silicone rubbervulcanized by novel crosslinking agent of polysilazane was studied. The experimental results showed that RTV silicone rubber samples vulcanics by theKH--CL crosslinking agent had the resistant temperature up to 350 ℃and theactivation energy of thermal degradation reaction of the vulcanizates increased to330KJ/mol. This Aught be attributed the elimination of the degradation ofsilo-cane chain initiated by the residual catalyst and the silanol groups in the vulcanizates.
