Abstract:
The present invention further relates to a particulate superabsorbent polymer composition comprising a crosslinker composition that is the reaction product selected from (i) saturated amines and/or saturated polyamines with ethylenically unsaturated glycidyl compounds and/or ethylenically unsaturated polyglycidyl compounds, (ii) ethylenically unsaturated amines and/or ethylenically unsaturated polyamines with saturated glycidyl compounds and/or saturated polyglycidyl compounds, or (iii) ethylenically unsaturated amines and/or ethylenically unsaturated polyamines with ethylenically unsaturated glycidyl compounds and/or ethylenically unsaturated polyglycidyl compounds; and a surface crosslinking agent applied to the particle surface. The present invention further relates to an absorbent article that includes such particulate superabsorbent polymer compositions.
