LAYERED CLAY MINERAL AND RUBBER COMPOSITION INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a layered clay mineral that has excellent dispersibility into rubber and can improve the physical properties of the rubber. SOLUTION: A layered clay mineral is organically modified by ion-bonding an organic compound bearing (1) ammonium, (2) imide and (3) at least one of polymerizable residual group selected from butadiene, isoprene and butene to the layered clay mineral and the organically modified layered clay mineral is added to rubber to provide a rubber composition including the organically modified layered clay mineral.
