Stabilized aqueous polymer compositions and their use

摘要

Disclosed are stabilized aqueous polymer compositions containing A) a stabilizing amount of a least a sulfur dye or containing a stabilizing amount of a sulfur dye with a compound comprising a heterocyclic system containing nitrogen and sulphur as ring heteroatoms and B) at least one polymer comprising groups which are capable of complex formation with ions. The aqueous polymer compositions are stabilized against thermal or other degradation processes of the polymer by addition of component A) to allow their use even under harsh conditions.
