PP-III-23The introduction of 5 parts by weight of the liquid polyketone into initial raw rubbercompound does not virtually change its vulcanization-kinetic and physico-mechanicalcharacteristics. After vulcanization of the rubber compound, characteristics of the resultingrubber were tested. Addition of polyketone was shown to increase the strength of rubbercoupling with metal cord. Presumably, this is due to efficient interaction of polar carbonylgroups of polyketone, which is present in the rubber compound, with brass coating of thecord. Such physico-mechanical properties of rubber as hardness, elasticity, and frostresistance remain unchanged. The study performed indicates good prospects of using theliquid polyketones for the improvement of operating characteristics of the rubber-cordsystems.This work was supported by RFBR grant no. 06-03-08156-ofi.Reference1.
