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 adding1,2-PB.The optimized formulation and process were as follows:the addition level of MAH was 5phr,1,2-PB was 6phr,initiator DCP was 0.2phr,reaction temperature was 135 ℃,rotor speed was 50r·min-1 and reaction time was 4min.
