| Abstract: |
| The relationship between the activation energy of vulcanization and the properties of blend was discussed. The activation energy of vulcanization of CPE/NBR blend was obtained using Arrhenius formula. The results showed that the physical properties of the blend were com-parable to the compromised properties of the two rubbers when the activation energy of the blend was close to that of CPE or NBR with the same curing system. The thiourea/sulfur/super acce-lerator system was suitable for CPE/NBR blend. The vulcanizate with good oil resistance and ten-sile properties was obtained when the blending ratio of CPE/NBR was 80 : 20. |
