| abstract |
One of the purposes of the present invention is to provide lignin modified with a plant-derived compound, the modified lignin exhibiting, as a result, excellent curability and a high rubber reinforcing effect. Furthermore, the present invention provides a rubber composition that achieves improvement of molding properties or a modulus of elasticity, while maintaining a high degree of plant derivation. Provided is a modified lignin derivative obtained by modifying a lignin derivative with a plant-derived compound. In one or more embodiments, the plant-derived compound contains at least one of tung oil, linseed oil, cashew oil, and tall oil. |
