摘要：

Interactions of carbon black with nitrile rubber (NBR) and carboxylated nitrile rubber (XNBR) were studied by measurements of bound rubber, physical and dynamic mechanical properties of the vulcanizates and Monsanto rheometric studies on the rubber-filler mixes. Compared with NBR, XNBR shows a higher degree of interaction with the filler and oxidation of the filler surface increases the extent of the rubber-filler bonding, which involves weak hydrogen bonding and Van der Waal's forces. In the case of XNBR additional chemical bonding occurs between the -COOH groups of the rubber and the reactive groups on the filler surface.
