ABSTRACT:
The aqueous polymer composition comprises a water soluble polymer having a molar weight of at least 104Daltons 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.
