“…Figure 2 shows the Izod impact strength plotted against the PB rubber content for the different PVC/ABS blends prepared at milling temperatures of 165°C and 180°C. The impact strength of blends increased together with the PB rubber content as expected from previous studies [14,17,18]. At low PB rubber contents, all of the notched impact strength of brittle blends occurred in the range of 50-200 J/m, independent of the type of PVC resin used.…”

Abstract Acrylonitrile-butadiene-styrene (ABS) grafted copolymer prepared by emulsion polymerization was used to modify different molecular weight poly (vinyl chloride) (PVC) resins. The effects of the molecular weight of the PVC resins on dynamic mechanical analyses (DMA) of PVC/ABS blends and matrix plasticizing behavior on the impact mechanical properties and the morphology were investigated. The tan δ peaks of PVC/ABS blends occurred at the same temperature obtained by DMA, indicating that miscibility of PVC/ABS blends was independent of the molecular weight of PVC. The notched Izod impact test results indicated that the amount of polybutadiene (PB) rubber needed for the brittle-ductile transition (BDT) increases together with the molecular weight of PVC when milled at 165°C. Increasing the operation temperature and adding the plasticizer dioctyl phthalate (DOP) could change the matrix plasticizing extent and the BDT. At a milling temperature of 165°C, the BDT was reached only with 3.6 wt% PB when DOP was added, in contrast to the addition of 7.2 wt% PB in the absence of DOP. The morphology of different plasticized degree of PVC/ABS blends was studied by transmission electron microscopy (TEM) showing that the PVC-1/ABS blends milled at 165°C showed a larger unstained area than the other series of PVC blends.

A low-molecular-weight liquid epoxidized natural rubber (LENR) was prepared through photosensitized degradation of epoxidized natural rubber with 50 mol percent of epoxy content (ENR-50). LENR was modified into hydrogenated liquid epoxidized natural rubber (HLENR) via in situ thermal degradation of arylsulfonyl hydrazide as a hydrogenating agent. The chemical structures of LENR and HLENR were characterized using Fourier transform infrared (FTIR) and 1 H nuclear magnetic resonance (NMR) spectroscopies. The thermal behaviour of LENR and HLENR were analysed using thermogravimetric analysis (TGA). The molecular weight and polydispersity index (PDI) of LENR and HLENR were determined using gel permeation chromatography (GPC). The parameter studies on the hydrogenation of LENR were investigated based on the source of diimide, weight ratios of LENR: p-toluenesulfonyl hydrazide (TSH), temperature, reaction time and solvent of the reaction. The highest conversion of hydrogenation was achieved at 130 °C for 4 hours reaction time, with 1:1 weight ratio of LENR: TSH using oxylene as a solvent.

“…The main purpose for grafting is to make the fiber hydrophobic and this enhances the compatibility, as well as dispersibility of the grafted fibers in the nonpolar matrices. Grafting of lignocellulosic material such as sisal fiber, jute, kenaf, wool, pineapple leaf, talc, starch and coir has been done successfully using different types of initiators [13][14][15][16][17]. A number of researches were conducted on grafting of palm fiber [18][19][20], however, no work has been done on polystyrene grafted OPFEB fiber.…”

Polystyrene was grafted onto oil palm empty fruit bunch (OPEFB) fiber in aqueous medium by using the H 2 O 2 /Fe 2+ system as an initiator. Optimization of the reaction conditions was carried out by varying the reaction period, temperature, amounts of the monomer, initiator and co-catalyst. The presence of the peaks around 3026 cm -1 , 698 cm -1 and 755 cm -1 in the Fourier transform infrared (FTIR) spectra of the grafted product and the presence of polystyrene on the surface of grafted OPEFB in the scanning electron micrograph provided strong evidence of the grafting. The maximum percentage of grafting (about 200%) was achieved when the reaction was carried on for 4 h at a temperature of 65°C, using 52.27 mmol monomer, 6.00 mmol initiator and 0.26 mmol co-catalyst. The thermal stability of the grafted OPEFB was found to be better than that of the ungrafted fiber, as seen from thermogravimetric analysis (TGA).
