THE EFFECT OF TECHNOLOGICAL FACTORS ON ELECTRIC-CONDUCTIVITY OF FILLED SILICON ELASTOMERS

There is effect of some technological factors (kind and content of fil lers, olygomer additions, vulcanization method) on the technical chara cteristics of filled silicon rubbers on the polydimethylvinylsiloxan ( SKTN) base investigate. It is established that these factors essential ly influence the microstructure of composites and connected with its c onductive network. It has been shown that the higher indexes belongs c omposites which are produced by the method of filling polymerization a nd especially with using alteration by various siliconorganic componen ts of thermally splitted graphite. The density of vulcanization networ k is estimated by the application of sol-analysis method, while NMR me thod is applied for a estimation of macromolecules in the composites a nd sensitivity of materials to external deformation.
