| Abstract: |
| The percolation thresholds and critical exponents of the crosslink networks in the vicinity of critical translation were obtained respectively by analyzing the vulcanization and the crosslink density curves of NR，BR and SBR with the aid of percolation theory.The results showed that，by usingthe same characterization method in the same vulcanization period， the critical exponents for these three types of rubber were similar， which indicated the evolutions of their crosslink networks in vulcanization process obeyed the same scale law. |
