“…The continuous phase is polypropylene, while the dispersed phase is thermoplastic starch (TPS). It can be seen that TPS particles are homogenously dispersed in the PP matrix, and both phases are well bonded to each other [13,14]. The good compatibility between them could be attributed to the chemical affinity between TPS component in starch-g-PP and KF.…”

Abstract. Starch-grafted-polypropylene (starch-g-PP)/kenaf fibres composites were prepared by melt compounding and compression molding. Polypropylene-grafted-maleic anhydrides (MAgPP) were added at different weight contents (1, 3 and 5 wt. %) as compatibilizer. The morphological, thermal and mechanical properties of the composites were characterized using thermogravimetric analysis, scanning electron microscopy, tensile and flexural test. The results indicated that mechanical properties of the composites were improved by addition of compatibilizer. From TGA, the thermal stability of the composites with MAgPP was improved compared with the composites without MAgPP. Finally, scanning electron microscopy of fractured surface revealed better adhesion between the fibers and matrix with presence of compatibilizer.

“…The copolymerization process of potato starch and benzyl methacrylate monomer was carried out in a three necked glass flask (100 cm 3 ) equipped with a mechanical stirrer, a thermometer and a nitrogen gas inlet. The 2.5 g of potato starch and 50 cm 3 of distilled water were heated at 80°C for 30 min.…”

“…Among biopolymers, polysaccharides such as starch, cellulose, xyloglucans, pectins and chitosan are of great industrial and academic interest as materials suitable for the physical, enzymatic and chemical modification due to their valuable properties such as low cost, availability, nontoxicity, low environmental pollution or renewability [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

The physicochemical properties such as swelling in polar and non-polar solvents, moisture resistance, chemical resistance, ability for gelatinization and the thermal properties along with the evolution of volatile decomposition products of some starch-g-copolymers obtained through the grafting of benzyl methacrylate monomer onto potato starch have been studied. The chemical structure of copolymers was confirmed using ATR-FTIR analysis. The prepared materials were characterized by completely different properties than unmodified potato starch due to the covalent bonding of poly(benzyl methacrylate) chains onto starch backbone. The copolymers were not able to gelate; however, they exhibited higher swelling in non-polar solvents, lower swelling in polar solvents and higher resistance toward moisture, acid and base conditions than unmodified potato starch. In addition, DSC analysis showed that T g of copolymers was shifted to a little higher values as compared to T g of poly(benzyl methacrylate). The thermal stabilities of copolymers and potato starch were comparable. Their decomposition took place in two main stages connected with the emission of various volatile decomposition products (CO 2 , CO, H 2 O, CH 4 , aldehydes, alcohols, furan derivatives, acids, benzyl methacrylate) in inert atmosphere as it was confirmed based on the simultaneous TG/DSC/ FTIR analysis.

“…This polymer is semi-crystalline, depending on its stereochemistry and processing conditions [4][5][6][7], and suitable for a wide range of industrial processing technologies, as injection moulding, blow-moulding, thermoforming, cast film and others [8]. However, in spite of promising properties, the bio-based plastics rarely meet the very demanding requirements of automotive industry [9]. Consequently, solutions are investigated, such as fibre reinforcement, to improve their mechanical performance.…”

Abstract. Low odour-emissive polylactide/cellulose fibre biocomposites, intended for car interior, were prepared and characterised. The impact of the different stages of processing (drying cycles, compounding, injection moulding) on the extent of polylactide degradation and on biocomposites properties was investigated by size exclusion chromatography, thermogravimetry, differential scanning calorimetry. In parallel, the odour emission of these materials was quantified via dynamic dilution olfactometry and Field of odours ® method. The changes in molecular weight and global odour emission indicated that compounding had a strong impact on polylactide degradation and odour emission, while injection moulding had no significant impact. Adding 0.5 wt% of an absorbent agent based on poly(1-methylpyrrol-2-ylsquaraine could) divide the global odour concentration by a factor 2. The morphology, mechanical and thermal properties of injection moulded PLAbiocomposites were not affected by the presence of the absorbent agent.
