“…Physically and chemically bound oleic acid of palm oil in polypropylene (PP) thermoplastics has been reported by Wirjosentono, et.al, to improve compatibility of the thermoplastics with cyclic natural rubber (CNR), [11]. Wirjosentono, et.al have used methcrylic acid and methacrylate comonomers as compatibilisers for PP/CNR blends, [12]. And Mahendra, et.al have utilised an adhesion promoters based on maleic anhydride-grafted polymers to improve compatibility of PP/CNR blends, [13].…”

Polyvinylchloride (PVC) is the second largest thermoplastics produced after polyethylene (PE), polypropylene (PP) and polystyrene (PS), especially for packaging, households, toys, and other commodity products. However when used for food packaging, PVC has to be plastisised using plastisisers (added upto 30%), which may not comply with safety requirements for food biofilms. Palm oil oleine (POO) is a nontoxic and edible triglyceride containing double bond and can be bounded onto PVC backbone in the presence of methylmethacrylate (MMA) as comonomer and benzylperoxide (BPO) as initiator. The PVC resin was dissolved in tetrahydrofurane (THF), added with POO, MMA and BPO, (in various compositions), under constant stirring in a reflux reactor. The reaction mixtures were then refluxed for 3 hours under nitrogen atmosphere at constant pressure 1 atm. Plastisised PVC films were obtained after casting the reaction mixtures on a glass plates, and dried under vacuum at constant temperature 40°C. Mechanical properties of the films were tested and their morphology were analysed under scanning electron microscope (SEM) and FTIR spectoscopy. Optimum clear and flexible PVC films was obtained when weight composition of the reaction mixture: PVC/MMA/POO/BPO: 2/0.5/0.5/0.35. Elongation at break of the optimum film was more than 95% higher, whereas the tensile strength was 60% lower when compare to those of pure casted PVC film. SEM analysis of the film surface also showed good homogenous morphology, whereas analysis of FTIR spectra of the films before and after exhausted washing in n-hexane, indicating 48.5% binding of MMA and POO in the PVC films.

“…have reported preparation of maleic anhydride-grafted polymers as adhesion promoters for polypropylene-cyclic natural rubber blends, [13]. Wirjosentono et.al have incorporated various comonomers: such as methacrylic acid and methylmethacrylate to improve grafting efficiency of oleic acid onto polypropylene-cyclic natural rubber blends, [14], [15]. Another benefit of utilization of biomass-based filler in polymer composites was for sound and vibration damping materials, [16].…”

Primary sludge as main byproduct wastes in a pulping industry still contain some biomass and potentially affects the environment when was not handled properly. The pulp industry primary sludge (PIPS) can be processed as microfiller for polystyrene-based foam composites for various engineering applications, such as sound and vibration damping materials. The PIPS has been dried, milled and shieved to 100-400 mesh particle sizes. Physical and chemical properties of the PIPS have been tested using: particle size analysis (PSA), FTIR spectroscopy, then its thermal properties using differential scanning calorymetry (DSC). Incorporation of the PIPS microfiller in maleic anhydride-modified polystyrene (MA-m-PS) matrices for composite foam was carried out in a reflux reactor in xylene solution using Tween 80 as surfactant under stirring. The composite foam was characterized, firstly based on their densities compared to that of fresh PS resin, then using electron microscopy (SEM) for morphology properties. It was found that mean particle size of the dried and milled PIPS powder was 14.84 μm and its biomass content was 10.5%. Result of FTIR spectroscopy showed that many of the selected characteristic bands of lignocelluloses overlap, specifically, the selected band 1366 cm-1 for cellulose is very close to the 1368 cm-1 selected for hemicellulose. Whereas result of and its decomposition temperature 549.86°C with heat of combustion 16.34 cal/g, which indicating suitability of the PIPS powder as filler for polymeric foam microcomposites. The result of morphology analysis of the PIPS-filled microcomposites foam based on MA-m-PS (optimum weight ratio of MA-m-PS/PIPS: 80/20, density 0.88 g/cm3), using SEM showed that PIPS microfillers were well distributed within the MA-m-PS matrices.

As filler of nanocomposite, NCC has been used in various kind of polymer matrices, such as polypropylene (PP), polyurethane (PU), poly(lactic acid)/polyamide and others [5][6][7][8][9][10][11] . The application of NCC as filler is only suitable with hydrophilic polymer and this property make NCC become incompatible with the hydrophobic polymer matrices 12 .…”

The oil palm's nanocrystalline cellulose (NCC) has been successfully isolated and characterized, also it has been applied in the emulsion system of cyclic natural rubber (CNR). Nanocrystalline cellulose (NCC) has been isolated and characterized from the lower part of empty fruit bunches (LEFB) by acid hydrolysis and followed by ultrasonication treatment. The obtained NCC has characteristic, such as (i) the crystallinity index of NCC was 77.84% and the dimension of NCC was 30-450 nm and 20-35 nm of length and width, respectively. The utilization of NCC in the emulsion's system of CNR can improve the stability of the emulsion system that measured by ESI value. The emulsion's system of CNR has divided into two groups based on the type of surfactants, such as Tween 80 and Lutrol F127. In the emulsion that prepared by Tween 80, at 28 th days after the addition of NCC (2-29% of fibril dosages), the ESI value was in the range 70-100% and linear with the fibril dosages.
