Patent ID: 8569392

Claim:
A method for making an absorbent for metal including the steps of: providing a composition of a first monomer and a composition of a second monomer; wherein the composition of the first monomer includes the first monomer and a solvent; wherein the composition of the second monomer includes the second monomer, an initiator and a cationic dispersant; wherein the cationic dispersant is a mixture of a material selected from the group consisting of 2-(methacryloyloxy)methyl-trimethylammonium chloride, 2-(methacryloyloxy)ethyl-trimethylammonium chloride, and 3-methacryloxy-propyl-trimethoxysilane with a material selected from the group consisting of hydrochloric acid and sulfuric acid; introducing the composition of the second monomer in the composition of the first monomer; and executing a microwave reaction to provide micro-balls of the absorbent for metal.
