Oxidation resistant polymeric thickeners and method relating thereto.

摘要

The present invention relates to polymeric thickeners which are stable in the presence of oxidizing agents or the like. More specifically, the preferred thickeners of the present invention are directed to polyacrylic-type polymeric thickeners, wherein the thickener can be place in a .15 molar aqueous solution of an oxidizing agent at 25 DEG C for greater than 60 days without exhibiting phase separation or a loss in viscosity of greater than 50%, whereby the oxidizing agent has an oxidation potential of greater than .75 volts and less than 1.0 volt.
