Absorbent hydrophobic boronate galactomannan complexes and process for producing same

摘要

Absorbent boronate-galactomannan complexes comprising a hydrophobic group are disclosed. The boronate-galactomannan complexes are solid materials capable of gel forming upon contacting with liquids. The boronate-galactomannan complexes are particularly suitable for absorbing liquids.
