| 中文摘要: |
| 研究抽出物对氯丁橡胶（CR）及其并用胶玻璃化转变温度（Tg）的影响。结果表明：抽出物对不同种类橡胶Tg的影响趋势不同。对于CR/顺丁橡胶（BR）/天然橡胶（NR）并用胶（硫化胶），抽出物使BR的升高，使CR和NR的Tg降低；而对于CR/BR/NR并用胶，抽出物对NR的Tg降低作用小于对CR的Tg降低作用；对于不同的橡胶材料，抽出物对其Tg的影响程度不一样，抽出物对CR生胶的Tg影响不大。 |
| 英文摘要: |
| Effect of the extractive on the glass transition temperature（Tg） of chloroprene rubber（CR） and its blends was studied.The results showed that the influence trend of the extractives on the Tg of different types of rubber was different.For CR/butadiene rubber（BR）/natural rubber（NR） blend（vulcanizate），the extract increased the Tg of BR and decreased the Tg of CR and NR.For CR/BR/NR blend（vulcanizate），the extract had a smaller effect on the decreasing Tg of NR than on that of CR.For different rubber materials，the impact of the extractives on their Tg varied，and the extractives had little effect on the Tg of CR raw rubber. |
