| Summary: | Compounds and vulcanisates of acrylonitrile-styrene-butadiene rubber (NSBR) were prepared, and their properties were compared with those of conventional blends between styrene butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR). Results reveal discrepancyin cure behaviour of NSBR from SBR/NBR blends to some extent, i.e., the NSBR yields inferior crosslink density to the SBR/NBR blends, and thus thehardness. By contrast, the cured NSBR specimens offer superior tensile strength and processability. Payne effect as an indication of filler network formation magnitude is slightly greater in the NSBR system. In summary, it is possible to substitute the SBR/NBR blends with single NSBR eliminating the complexity in blending process while giving advantageous processability and tensile strength. |
