A Study the Effect of Some Electrical Prosperities on Synthetic Rubber Reinforced with Carbon Black

In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced with black carbon show that the electrical conductivity is increased with increasing of concentration and both of molar conductivity and degree of dissociation are decreased with increasing of concentration, the results of effecting of temperatures on electrical properties show for Buna rubber increased with increasing of concentration and these results suggest there is association between rubber and solvent molecules and also there is association between rubber molecules it self . ١ ا 2!< +ود58 $اوا ي % ة آ 3 ر آور9, ه ت K,5+ 7 ةر ه ./ ا ط 1( ا نا ,و ,5 * ا Q *$ا 8 7 > % ن ا د @آ * % 8 دا 8 Q ا ف S E ./% ا ( لTLو وا ،7V ا ( H ">% * % 8 ,و ( آ دا 8و فو W ط 1( ا 8و G8 ةد ,ز وا ، * ا *L ، , V ا (آ ت Lا ./ ا ط 1( ا ج %3ا + . أ Y ي ا ا ر 1% ا O > و 1 ا ط 1( ا ق * ./ ا ط 1( ا ) [ آر آ مد] ل] 9 1983, ( . ^ . ا 78 8ا
