A Composition of a color Stable superabsorbent Polymer; an article that includes; a method for producing Said Composition and a method for Preventing discoloration of superabsorbent Polymer particles

摘要

A Polymer composition comprises a color Stable superabsorbent superabsorbent Polymer, an inorganic reducing Agent from approximately 0.05 and approximately 5 mol%, and a metal Salt of between approximately 0 and 2 mol% based on the amount of Superabsorbent Polymer present in the composition.The Polymer Composition and color Stable superabsorbent resistant color degradation during long periods of storage, even at a low temperature and high humidity.A method of Manufacturing the color Stable superabsorbent Polymer composition comprises the steps of: (a) forming a mixture comprising Water and at least one monomer; (b) polymerizing the mixture to form a hydrogel, and (c) add the hydrogel formed in STEP (b), on the basis of the mo The monomer present in the step (a), between approximately 0,05 and approximately 5 mol% of a metal Salt, and between about 0.05 and approximately 5 mol% of an inorganic reducing Agent. Method for Preventing discoloration of superabsorbent Polymer particles.
