摘要:	The mechanical properties of Nylon 6,6 blended with recycled scrap material, polyvinyl butyral (PVB), using maleated styrene-ethylene-butylene- styrene block copolymer ( SEBS-g-MA) as a compatibilizer are discussed. Control samples of Nylon 6,6/PVB blends and Nylon 6,6/SEBS-g-MA blends were also compared. The results show Nylon 6,6/PVB blends give higher tensile strength than Nylon 6,6/SEBS-g-MA blends. As for Nylon 6,6/SEBS-gMA/PVB blends, impact strength increases with increasing the dosage of SEBS-g-MA. PVB improves flexural and tensile properties but sacrifices impact strength of the blends. Meanwhile, the ductile-brittle transition temperature (DBTT) increases with increasing PVB content. Through morphology observation, hole sizes are smaller with increasing SEBS-g-MA content. In summary, suitable amounts of PVB scrap are vital to balance both rigidity and toughness of blends. This study helps to understand the role of PVB in Nylon 6,6 blend systems, which allows PVB to find a practical application based on economic and environmental concerns.
