ジエン系ポリマーの耐摩耗性の改良 Improvement of Abrasion Resistance of Polydiene
The tire test was carried out by twelve tires, which were made of various BRs and SBRs. From these results, the overpowering correlation was glass transition temperature with abrasion resistance. Sn coupled SBR reacted with carbon black (CB), and the bound rubber was increased than that of the non-modified SBR, so the abrasion resistance was improved. CB was very well dispersed in the SBR. On the case of silica filled compound, the modified SBR with SiOR group reacted with silica, and the abrasion resistance was also improved. A method to introduce a functional group into high <i>cis</i>-BR was developed recently, and the abrasion resistance of the modified BR was improved. We reviewed about these functional group introduction methods and abrasion resistance.
