Summary: This study aimed to replace EPDM and carbon black with microcrystalline cellulose (MCC) and lignin in specified amounts to investigate the properties of EPDM elastomers. The results showed that the introduction of MCC and lignin increased elastic modulus and tear strength, but decreased tensile strength. Minor chemical shifts and lower thermal stability were observed. In addition, MCC and lignin facilitated the vulcanization process and dispersed homogeneously in the matrix. All mechanical values were within the specified standard after the replacement of MCC and lignin.

Summary: The molecular weight of lignin decreased and its distribution narrowed after alkaline depolymerization or solvent extraction pretreatment, leading to an increase in phenolic hydroxyl group content. Lignin extracted with ethyl acetate showed the lowest molecular weight and highest phenolic hydroxyl group content, demonstrating better free radical scavenging ability than commercial Irganox1010. The alkali lignin extracted with ethyl acetate significantly improved the antioxidant performance of SBS elastomer, comparable to that of Irganox1010, indicating great application potential.
