| Abstract: |
| The influence of the blending ratio of EVM/NBR and the sulfur and tert-butyl phenolic resin（2402 resin）curing system on the properties of blend was investigated and the properties of the dynamically vulcanized blend was compared with those of the statically vulcanized blend. The results showed that the blending ratio had a significant influence on the physical properties of the blend；when NBR was dynamically prevulcanized，the die swell of the blend decreased significantly，the aging property improved and the effect of the sulfur and 2404 resin curing system on the vulcanization of EVM decreased resulting in the coexistence of multi-curing systems in the blend. The DSC analysis showed that the dynamically vulcanized EVM/NBR blend had only one Tg which was between Tg of EVM and Tg of NBR confirming the good compatibility between EVM and NBR. |
