| Abstract: |
| The abrasion properties，morphology and microstructure of SBR vulcanizates with three different structures were studied by analysing their infra-red spectras before and after abrasion, and their SEM cross-section pictures.The results showed that the abrasion process was a mechano-chemical reaction including active chain-oxydized reaction initiated by the mechanical force；the more the main chains and monosulfide bonds in the molecule broke in the abrasion process,the more the quantity of ether bonds produced,the poorer the abrasion properties and the rougher the abrasion surface. |
