Abstract:
The present invention aims to provide a rubber composition having sufficient reinforcement and fatigue resistance even when a large strain is applied thereto, and the present invention is to provide a substituted carboxy group-containing modified cellulose nanofiber wherein at least part thereof has at least any one of a substituent represented by Formula (a): —CONH—R1 and a substituent represented by Formula (b): —COO—R1 (in Formulae (a) and (b), R1 is independently a C3-30 hydrocarbon having at least one unsaturated bond), and a rubber composition including the same.
