Abstract
This disclosure generally relates to liquid compositions that are suitable to provide absorbent materials (e.g., hydrogel coating compositions), and methods of preparing the compositions and absorbent materials thereof. The compositions can include a first polymer type including one or more acrylate polymer, a second polymer type including one or more non-acrylate polymer, a crosslinking agent, and water. The compositions are suitable to provide an absorbent material having a water absorption capacity of at least about 50 grams of water per gram of absorbent material.
Claims23
A liquid composition comprising:
- a first polymer type comprising one or more acrylate polymer,
- a second polymer type comprising one or more non-acrylate polymer,
- a crosslinking agent, wherein the crosslinking agent is suitable for crosslinking the acrylate polymer of the first polymer type, the acrylate polymer of the first polymer type with the non-acrylate polymer of the second polymer type, the non-acrylate polymer of the second polymer type, or a combination thereof, and
- the crosslinking agent is selected from polyepichorohydrin amines, quaternary amines, amides peroxides, peroxodisulfate, photoactive transition metal catalysts, brominate acrylates, polyaldehydes, and propenyl compounds;
- and
- water;
- wherein the liquid composition is suitable to provide an absorbent material having a water absorption capacity of at least about 50 grams of water per gram of absorbent material.
