Abstract: |
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. |
