| Abstract: |
| The cracking mechanism of waste rubber was studied by thermogravimetric-derivative thermogravimetric analysis and thermogravimetric-differential scanning analysis of NR，BR，SBR，BIIR and NR/BR/SBR/BIIR blends. The results showed that the cracking reaction process of NR and BIIR was similar，which had only one obvious mass loss process and one peak mass loss rate. The cracking reaction process of BR and SBR was similar，which was divided into two stages. The first stage had a small mass loss，and the second stage had a larger mass loss. The cracking reaction process of NR/BR/SBR/BIIR blends was similar to that of BR，and the characteristic temperature of the cracking reaction was close. |
