  • Patent number: 11884824
    Abstract: A thermoplastic acrylonitrile containing copolymer/lignin blend, e.g., thermoplastic acrylonitrile-butadiene-styrene copolymer/lignin blend, is provided, whereas the blend comprises (i) an amount of thermoplastic acrylonitrile containing copolymer (e.g., acrylonitrile-butadiene-styrene copolymer); (ii) an amount of lignin; (iii) an amount of compatibilizing agent, such as phthalic anhydride, capable of imparting improved ductility and impact strength to the resultant blend and (iv) optionally an amount of at least one additive to impart specific properties including, but not limited, to resistance to ultraviolet radiation, resistance to oxidation, flame retardance, color, surface friction, or surface static charge accumulation. Methods of improving impact strength and/or ductility of, for example, a thermoplastic acrylonitrile-butadiene-styrene copolymer/lignin blend and articles made therefrom are also disclosed.
