  • Publication number: 20230174784
    Abstract: The present invention relates to a thermoplastic composition, a thermoplastic composite, and a method for producing the thermoplastic composite. In the method for producing the thermoplastic composite, a polymer, an acid-modified lignin with a specific element content and a compatibilizer with a specific melt flow index and a specific maleic anhydride content are used to produce the thermoplastic composite. Hydroxy groups of the acid-modified lignin react with maleic anhydride groups of the compatibilizer to generate ester bonds via an in-situ reaction catalyzed by acidic groups of the acid-modified lignin to enhance compatibility between the polymer and the lignin, thereby increasing a mechanical strength of the resulted thermoplastic composite.
