  Polymer thickeners having a viscosity of at least 10 K, employed in acid media are stabilized with Redox indicators having from 6 to 30 carbon atoms, such as, for example, methylene blue, phenosafranine, pyronine Y, tartrazine, amaranth, methyl orange, and alkali metals salt of diphenylamine sulfonate and malachite green oxalate, which stabilizers are combined with the polymer in a concentration of between about 0.005 to about 1 weight %.

  在酸性介质中使用的粘度至少为 10 K 的聚合物增稠剂可使用具有 6 至 30 个碳原子的氧化还原指示剂进行稳定，例如亚甲基蓝、苯并呋喃、吡咯宁 Y、酒石酸、苋菜、甲基橙、二苯胺磺酸盐的碱金属盐和孔雀石绿草酸盐，这些稳定剂与聚合物的混合浓度约为 0.005 至 1 重量％。
