This research prepared poly(lactic acid) (PLA) and PLA/acrylonitrile-butadiene rubber (NBR) blends before and after adding polyethylene-g-maleic anhydride with 3 wt% of maleic anhydride (PE-g-MA3) 3 phr. The effects of NBR and PE-g-MA3 on morphological, mechanical and thermal properties of PLA and PLA blends were discussed. The morphological analysis observed the two-phase morphology of PLA/NBR blends, and it was observed the cavities generated due to NBR phase detachment during sample fracture, and droplets of NBR phase at higher NBR content. The PE-g-MA3 addition could improve adhesion between PLA and NBR phases due to the decrease of cavities in PLA matrix and droplet size of NBR. The mechanical properties showed the impact strength and strain at break of PLA/NBR blends dramatically increased when the amount of NBR increasing. The addition of PE-g-MA3 significantly improved the impact strength of PLA/NBR blends. The thermal properties showed the NBR addition had effect slightly on the melting temperature of PLA/NBR blends. The filling of NBR and PE-g-MA3 greatly decreased the percent crystallinity of PLA more than two times. The thermal degradation of pure PLA and NBR proceeds by one step, while the thermal degradation process of PLA/NBR and PLA/PE-g-MA3 proceeds by two steps. Which the first step showed a large mass loss of PLA degradation and the second step showed a small mass loss of PE-g-MA and NBR degradation.

Effects of 3-aminopropyltriethoxysilane (APTES) as coupling agent on thermal properties of Polypropylene/Palm Kernal Shell (PP/PKS) biocomposites were studied. PKS with different filler loading (5, 10, 15, 20 and 25 wt %) were added into polypropylene matrix and were compounded using hot melt blending method. Thermogravimetric Analysis (TGA) result shows a higher thermal stability of amino silane modified fillers (10% filler loading). Percentage of crystallinity for PP/PKS composites increased after adding amino silane due to better dispersion of filler and the ability of coupling agent to enhance compatibility between PKS and polypropylene hence it increases the nucleation site.

Acrylonitrile-butadiene rubber (NBR) or nitrile rubber is an unsaturated copolymer of butadiene and acrylonitrile. NBR has been widely used for fuel hoses, seals and gaskets due to its excellent oil and fuel resistance. Aiming to develop NBR which has resistance to oxygenated solvent, NBR with acrylonitrile content of 34 wt%, was blended with Acrylonitrile-butadiene-styrene (ABS) and Poly (Styrene-co-Acrylonitrile) (SAN) as binary polymer systems. The NBR/ABS and SAN blends were prepared by mechanical blending in the composition of 80/20, 70/30 and 60/40 w/w. The effects of ABS or SAN content on mechanical, morphological and thermal properties were investigated and compared with commercials NBR. Mechanical properties were determined using the tensile testing machine. The morphologies of polymer blends were investigated using scanning electron microscope (SEM). The thermal properties were examined using differential scanning calorimeter (DSC), thermal gravimetric analysis (TGA) and dynamic mechanical analysis (DMA). It has been found that percent compatibility of ABS and SAN into NBR rich phase are 2.69 and 1.53 wt% respectively.
