Abstract:
1. A method of forming an absorbing material comprising: supplying polymerized monomer, wherein the polymerized monomer is sourced from a monomer having one or more of the following structures: wherein R combining at least one of monomers (I), (II) and/or (III) with a solvent and partially neutralizing the carboxylic acid functionality at a level of 25.0 mole % to 85.0 mole % for each mole of carboxylic acid functionality present, wherein said partial neutralization takes place over an accumulated time period not to exceed 6.0 hours and at a temperature of 50.0° C. to 150° C.; polymerizing one of said monomers (I), (II) and/or (III) to form polymerized monomers wherein the percent conversion of one of said monomers to polymer is at or above 50.0%; and combining one of said polymerized monomers as component into an absorbing material.
