ACTIVITY OF CARBON-BLACK AS A FILLER IN DIFFERENT ELASTOMERIC MATRICES

Activity of carbon black toward natural, butyl, butadiene, butadiene-s tyrene and butadiene-acrylonitrile rubber has been evaluated. Peroxide , sulfur donor, sulfur/accelerator systems and also tris(2-methyl-1-az iridinyl)phoshine oxide as crosslinking substances were used. Differen t activity parameters were taken into consideration. From the results it follows that activity of carbon black depends not only on its prope rties but also on the type of the elastomer matrix. An effect of chain flexibility, unsaturation degree, crosslinking density and chemical s tructure of the network has been observed.
