Abstract: Residual chloromethyl groups in methylene-bridged aromatic polymer adsorbents are susceptible to hydrolysis to benzyl alcohol groups and oxidation to benzoic acid groups. The introduction of these hydroxyl and carboxylic acid groups contributes to the water adsorption capacity or hydrophilicity of these adsorbents. Unfortunately, this hydrophilicity interferes with the utility of these resins as adsorbents for volatile organic compounds. By capping these residual chloromethyl groups with hydrophobic aromatic compounds prior to their opportunity to hydrolyze or oxidize, the hydrophobicity of methylene-bridged aromatic polymer adsorbents is increased and their utility for the absorption of organic compounds is enhanced.

Abstract: Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with simple surfactants and hydrophilizing agent salts.
