STABILIZED AQUEOUS POLYMER COMPOSITIONS |
摘要 |
The aqueous polymer composition comprises a water soluble polymer having a molar weight of at least 10 4 Daltons and comprising functional groups which may form complexes with metal ions. The aqueous polymer compositions of this invention are stabilized against thermal or other degradation processes by addition of a phenothiazine compound to allow their use even under harsh conditions. |
