    摘要: High polymer content compositions, containing the neutralized salt of a carboxyl-containing polymer suspended in an organic medium, are made by neutralizing the carboxyl-containing polymer in the presence of a neutralizing agent and an equal quantity of already neutralized polymer in an organic medium. These compositions are useful as thickeners and emulsifiers for aqueous solutions.
