dc.description.abstractModification of natural rubber into Maleated Natural Rubber (MNR) is one of research area that is still developing. This research is aiming to study the impact of variety of concentration maleic anhydride (MAH) and the temperature of mixing for MNR making in order to determined the degree of grafting of MAH. MAH was varied by 6, 8, and 10 phr (per hundred rubber) while the temperature was varied by 135, 145 and 155 oC. The process Modification is using internal mixer with 60 rpm for 10 minutes. The degree of grafting was determined by titrimetric method where MNR diluted in xylene and titrated by MeOH until the color solution was changed. Based on the test results by using FT-IR instrument. For natural rubber, C-H is clinging to double bond C=C at peak absorption 835 cm-1 and stretching characterisation of alkene (C=C) is at the peak absorption 1659 cm-1. And for the MNR, the absorption peak anhydride (C=O) were grafted on natural rubber is at the absorption peak 1712 cm-1. From degree of grafting analysis result, showing that the variety of concentration MAH can be grafted at natural rubber’s structure until reach optimum condition. And by increasing temperature, the degree of grafting for making the MNR is increasing . The highest degree of grafting obtained at 8 phr and 155 °C with the degree of grafting at 3.593%.en_US
