| 中文摘要: |
| 研究在氮气保护下，用邻二氯苯回流煮沸分解硫化胶，采用红外光谱（IR）法测试不同牌号溶聚丁苯橡胶（SSBR）并用胶、顺丁橡胶（BR）/SSBR并用胶和天然橡胶（NR）/SSBR并用胶的1，2-乙烯基和苯乙烯质量分数。结果表明：对于SSBR5251/SSBR6361并用胶和BR/SSBR并用胶，IR法与核磁共振（NMR）法的测定结果之间呈现良好的线性关系；而对于NR/SSBR并用胶，IR法与NMR法的测定结果之间不具备相关性。 |
| 英文摘要: |
| The decomposition of vulcanizate by boiling o-dichlorobenzene under nitrogen protection was studied，the mass fraction of 1，2-vinyl and styrene in different grades of solution polymerized styrene butadiene rubber（SSBR） blends，cis polybutadiene rubber（BR）/SSBR blends and natural rubber（NR）/SSBR blends were determined by infrared spectroscopy（IR）.The results showed that for SSBR5251/SSBR6361 blends and BR/SSBR blends，there was a good linear relationship between IR and nuclear magnetic resonance（NMR） test results，and for NR/SSBR blends，there was no correlation between IR and NMR test results. |
