PVC-g-MA has been synthesized to replace the conventional PE-g-MA as the compatibilizer in PVC/ENR/kenaf core powder composites. The presence of the maleic anhydride grafting on PVC was made evident by infrared analysis. PVC/ENR/kenaf core powder composite samples were prepared using Haake Polydrive with the temperature of 140°C, with different kenaf core powder loading (5, 10, 15 and 20 phr) and incorporating PVC-g-MA with 4 phr. The water absorption and thermo-oxidative ageing properties of the composites were investigated. The results indicated that the percent of water uptake decreased with the incorporation of PVC-g-MA. The thermo-oxidative ageing test shows that the ageing properties of PVC/ENR/kenaf core powder composites with the addition of PVC-g-MA are lower compared to PVC/ENR/kenaf without PVC-g-MA.

Oxidative Ageing

An experimental study was conducted to investigate the influence of thermo-oxidative ageing on the tensile properties of PVC/ENR/KCP composites. Sodium dodecyl sulfate filler treatment was also carried out to evaluate the effect of filler treatment. The composites were prepared by melt compounding using Haake Polydrive internal mixer at 140 °C and 50 rpm. Compression-moulded samples were subjected to fracture surface morphology analysis and thermo-oxidative ageing for 3, 5 and 7 days. Thermo-oxidative ageing test indicates that after 3 days of exposure to heat, tensile strength increases, which is due to the further cross-linking reaction. With further exposure for 5 days and 7 days, the tensile strength is reduced probably due to the reduction in flexibility of the cross-link, which affect the stress distribution in the composites.
