Abstract
A fuel absorbent is provided in which polymer particles having a fuel absorbing ability are contained or dispersed in a binder matrix permeable to fuel. The fuel permeates the binder and is absorbed by the polymer particles. A process is provided for making the fuel absorbent by mixing polymer particles having fuel absorbing ability with a binder dissolved in a solvent, to thereby obtain a dispersion mixture having the polymer particles dispersed therein. The dispersion mixture is then dried to cause the polymer particles to be dispersed in a matrix of the binder. The fuel absorbent has excellent durability and fuel absorbing/desorbing ability.
