| Summary: | MAH grafted EPM is a highly potential compatibiliser in EPDM based blend. This studyjs
focusing on synthesizing peroxide-initiated MAH-g-EPM via melt grafting using a Haake
intemal mixer at high shear rate. The effect of MAH and dicumyl (DCP) percentage on the
grafting efficiency of MAH onto EPM chains was carried out through a 2-level factorial
experimental design using the Design Expert 6.0.5 software. The MAH and DCP content
were varied in the range of 1-5 phr and 0.1-0.3 phr, respectively. The grafting parameters
were fixed at temperature of 180°C, rotor speed of 60 rpm for 5 minutes. The grafting
efficiency was determined by Fourier Transform Infrared spectroscopy analysis based on
cumulative absorbance of anhydrides characteristic peaks. It was observed to be highly
'j 'f influenced by the amount of MAH and DCP and the optimum funtionalisation was achieved
at 5 phr MAH and 0.3 phr peroxide addition |
