| Abstract: |
| The clay was modified with ENR25 and ENR45 respectively .The interaction between ENR and clay，and the effects of the epoxidation state and addition level of ENR on the structure and properties of modified clay and clay-filled NR vulcanizate were investigated by determining the bound rubber content in mix，the appearant crosslink density，reinforcement and physical properties of vulcanizate.The results showed that the interfacial interaction between clay and NR was intensified，thebound rubber content in mix and the appearant crosslink density of vulcanizate were increased and the network structure and physical properties of clay-filled NR vulcanizate were improved by using ENR to modify clay. |
