Stabilized aqueous polymer compositions

摘要

Disclosed are stabilized aqueous polymer compositions containing
A) a stabilizing amount of at least a first stabilizer comprising a heterocyclic condensed ringsystem containing nitrogen and sulphur ring heteroatoms with the exception of a phenothiazine compound or containing a stabilizing amount of said first stabilizer with a phenothiazine compound; 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.
