    Transport behaviour of xylene through compatibilized low density polyethylene composite
    (U. P., 2017) Onuegbu, Genevieve C.; Onuoha, Chukwudike
    The transport behaviour of xylene through compatibilized low density polyethylene (LDPE) composite was investigated at different temperatures 40 0C, 60 0C and 80 0C. The kola nut used was ground to 25 µm particle size. In preparation of the composite, 0 – 5 wt% of kola nut powder and 0 – 2.5 wt% of the compatibilizer were thoroughly mixed with 200g of low density polyethylene in an injection moulding machine. The injected LDPE/Kolanut composites were taken for sorption test. The sorption data obtained for the composite at different temperatures investigated were expressed as the mole percentage uptake, Qt (mole %). Results showed that the mole percent uptake of xylene at the five filler contents (0 – 5 wt%) generally increased with increase in sorption temperature but decreased with increase in compatibilizer and filler content. This can be seen at 80 0C and 0, 1, 1.5 and 2.5 wt% of the comptbilizer respectively. The molar percentage uptake of xylene at 1 wt% of the filler yielded the following values; 8.7876, 8.5962, 8.4056 and 8.3111 respectively. At 2 wt5, it yielded 7.9812, 7.9104, 7.7423 and 7.7199 respectively; at 3 wt% it gave 7.8232, 7.6351, 7.5663 and 7.4652 respectively; at 4 wt%, it yielded 8.4120, 8.3315, 8.2132 and 7.9667 respectively and at 5 wt% it gave 7.9635, 7.8630, 7.6256 and 7.5013 respectively
