A lignin derivative that is extracted from biomass and is used for rubber reinforcement or for use in a molding material is provided. Such a lignin derivative has a number average molecular weight of 300 to 2,000, and contains a component that is soluble in a polar organic solvent, in an amount of 80% by mass or more. When such a lignin derivative is incorporated, a lignin resin composition, a rubber composition, or a molding material, all of which have excellent low hysteresis loss characteristics, elastic modulus, or tensile properties, can be obtained. Furthermore, when a component that is thermofusible is used as the soluble component, a lignin resin composition, a rubber composition, or a molding material, all of which have superior aforementioned characteristics, can be obtained.
本文提供了一种从生物质中提取的木质素衍生物,可用于橡胶补强或模塑材料。这种木质素衍生物的平均分子量为 300 到 2,000,并含有一种可溶于极性有机溶剂的成分,其质量分数为 80% 或以上。当加入这种木质素衍生物时,可获得木质素树脂组合物、橡胶组合物或成型材料,它们都具有优异的低滞后损失特性、弹性模量或拉伸特性。此外,当使用热熔性成分作为可溶性成分时,可获得木质素树脂组合物、橡胶组合物或成型材料,它们都具有上述优异特性。
