Highly-swellable absorption material with reduced caking tendency comprises an acid group-containing natural or synthetic polymer coated with a nitrogen-containing nonionic surfactant |
摘要 |
A highly-swellable absorption material with reduced caking tendency under moist and high temperature conditions obtained by heating a combination of a suitable acid group-containing natural or synthetic polymer and a N-containing nonionic surfactant coating agent. A highly-swellable absorption material with reduced caking tendency under moist and high temperature conditions obtained by heating a combination of: (i) an acid group-modified water- or aqueous solution-absorbing natural polymer or a water-insoluble optionally surface-crosslinked water- or aqueous solution-absorbing crosslinked polymer based on polymerizable, at least partly neutralized acid group-containing monomers; and (ii) a N-containing nonionic surfactant coating agent.
