| Abstract: |
| The self vulcanization of BR/CPE blend was investigated. It was found that the curing rate and the crosslink density could be significantly increased, and the gel content could reach 98% when the small quantity (0.5-2phr) of stannous chloride was used in the blend. The curing behaviour of blend and the property of vulcanizate were insignificantly influenced when more than 2 phr of stannous chloride was used. 30 phr of carbon black or silica was suitable for the BR/CPE blend. The better physical properties of the vulcanizate could be obtained when CPE was dominant in the blend. |
