| 中文摘要: |
| 研究配方和工艺对熔融法天然橡胶接枝马来酸酐（NR-g-MAH）接枝率和接枝效率的影响。结果表明：加入1，2-聚丁二烯（1，2-PB）对提高NR-g-MAH接枝率具有明显效果；马来酸酐用量为5份、1，2-PB用量为6份、引发剂DCP用量为0.2份、反应温度为135 ℃、转子转速为50 r·min-1、反应时间为4 min时，NR-g-MAH的接枝率和接枝效率较高。 |
| 英文摘要: |
| The influence of formula variables and process parameters on the grafting ratio and grafting efficiency of maleic anhydride grafted NR（NR-g-MAH） by melt grafting method was investigated.The results showed that the grafting ratio of NR-g-MAH was improved significantly by adding 1，2-PB.The optimized formulation and process were as follows: the addition level of MAH was 5 phr，1，2-PB was 6 phr，initiator DCP was 0.2 phr，reaction temperature was 135 ℃，rotor speed was 50 r·min-1 and reaction time was 4 min. |
