The paper studies the influence of multiwalled carbon nanotubes (MWCN) on vulcanizing and dynamic properties under shear and oscillating load. It was found that, despite the lack of preliminary preparation of MWCN, when their concentration increase the dynamic properties also increase under an oscillating load in highly elastic state. Thus, it is possible to use MWCN producing elastomer materials with improved properties.

The influence of carbon black N121 and N326, oxidized by active oxygen forms, in comparison with the influence of channel carbon black K 354 on the properties of rubbers based on butyl rubber was investigated. It was revealed that the introduction of oxidized carbon black samples into the composition of rubber compounds allows increasing the start time of rubber mixture scorching from 8.82 to 11.17 minutes, increasing the level of conventional tensile strength from 15, 52 to 16.68 MPa. It has been established that using rubber based on butyl rubber as a filler for carbon black N121 or N326, oxidized with 30% hydrogen peroxide, makes it possible to obtain rubber with a surface energy similar to rubber K 354.
