| Abstract: | Methyl methaacrylate (MMA) monomer and initiating agent were added at a proper rate into the system based on natural rubber latex and white carbon black. The monomer was grafted onto the sur-face of white black carbon and at the same time ligated with rubber macromolecule chain via chemical bonds. The natural rubber composites NR/WC/MMA filled with white carbon black were prepared by us-ing the latex co-precipitation method. This composite has a good processing fluidity, dynamic property and aging performance. |
