Interaction between Functional Groups in some Rubbers and Carbon

dehyde latex adhesives Swelling Butadiene copolymers with functional groups and channel carbon black K-354 have been investigated. Rubber compound based on styrene butadiene rubber SKMS-30ARKM filled with 55 phr combination of fur-nace carbon black (N 550 type) and K-354 was used. Tire cord was dipped with resorcinol formaldehyde la-tex adhesives based on above copolymers. The K-354 content increase in the rubber compound leads to the increase of the bond strength of rubber to cord which was dipped with adhesives based on copolymers with pyridine and amino groups in macromolecules. The K-354 incorporating in above adhesives leads to the ad-hesive films mechanical properties improvement but doesn't influence the bond strength. These results showed the possibility of the interaction of pyridine and amino groups in copolymers with K-354. Model systems copolymer ± K-354 were investigated. The swelling degree of these systems in the different sol-vents and the intensity (I) of the copolymer ± K-354 interaction were determined. I was evaluated by the difference I = (1/Sf)-(1/So), where Sf is the swelling de-gree of the filled sample and So is the same one of the unfilled sample. Solvents were used which selectively destroyed the copolymer ± K-354 bonds of different types. It was shown that pyridine and amino groups of copolymers form strong bonds with chinone groups of K-354, apparently of betaine type. The obtained re-sults open a possibility of improving rubber compo-sites mechanical and adhesion properties. Die Wechselwirkung zwischen funktionellen Gruppen in einige
