Abstract

This invention is directed to coated water-swellable materials, typically solid, particulate, water-swellable materials, i.e. materials that comprise hydrogel-forming polymers, whereof at least a part is coated with a coating, which substantially does not break when the polymers swell, as set out in the method herein. Said coating is present at a level of at least 1% by weight of the water-swellable material. The coating comprises preferably an elastomeric polymeric material. The invention also relates products, e.g. disposable absorbent articles, comprising such coated water-swellable material.

Claims (15)

1. A water-swellable material that comprises hydrogel forming polymers, coated by a coating formed from a coating agent comprising an elastomeric polymeric material, whereby said coating is present at a level of at least 1%
by weight of the water-swellable material, and whereby the water swellable material has a CCRC of at least 10g/g and whereby, for at least a part of the coated hydrogel forming polymers, said coating is non-breaking, when the water-swellable material is swollen to equilibrium in 0.9% saline solution by the method defined herein.
2. A water-swellable material as in claim 1 whereby said part of the coated hydrogel forming polymers that has a non-breaking coating of an elastomeric polymeric material is at least 60% by weight of the material, or even at least 80% or even at least 90% by weight of the material, having a coating with an elastomeric, polymeric material.
3. A water-swellable material according to claim 1 or 2, whereby the coating has an average thickness of at least lam, preferably at least 5µm, and more preferably at least 10µm.
4. A water-swellable material according to any preceding claim, which is a solid, preferably particulate water-swellable material and whereby said coated hydrogel-forming polymers are solid, preferably particulate.
5. A water-swellable material according to any preceding claim, whereby said coating agent comprises natural or synthetic elastomeric polymeric materials, preferably elastomeric polymeric material selected from the group of natural rubber, synthetic rubber and thermoplastic elastomers that are elastic at 35°C.
6. A water-swellable material as in claim 5, whereby said coating agent comprises polymers, co-polymers, and/or blockcopolymers of ethylene, vinyl compounds polyunsaturated monomers, polyurethanes, polyethers, polydimethylsiloxanes, and / or proteins, which may optionally be grafted and/or be (partially) modified with chemical substituent groups, preferably with hydroxyl substituent groups and/ or carboxylate substituent groups.
7. A water-swellable material as in any preceding claim, whereby said coating and/ or coating agent is hydrophilic.
8. A water-swellable material as in any preceding claims, whereby said material has a CCRC of at least about 20g/g, preferably at least about 30g/g.
9. An absorbent structure, suitable for disposable absorbent articles, comprising the water-swellable material as in any of claims 1 to 8.
10. Disposable absorbent article comprising the water-swellable material or absorbent structure according to any of claims 1 to 9.
11. A process for making the water-swellable material of claims 1 to 8 comprising the steps of:
a) obtaining hydrogel forming polymers; and b) simultaneously with or subsequently to step a), applying a coating agent comprising an elastomeric polymeric mateial to at least part of said hydrogel forming polymers to obtain coated hydrogel forming polymers; and preferably c) prior to, simultaneous with or subsequent to step b), obtaining said hydrogel forming polymers or coated hydrogel forming polymers in solid, preferably particulate, form.
12. A process according to claim 11, whereby the coating agent in step b) is fluid, in the form of a solution, a dispersion, or a hotmelt, and whereby step b) is preferably done in a fluid bed or Wurster coater.
13. A process according to claim 11 or 12, whereby step c) results in solid coated hydrogel forming polymers which are subsequently or simultaneously with step c) subjected to a temperature of at least 80° Celsius, preferably at least 100° Celsius, more preferably at least about 140° Celsius.
14. Use of the process according to claims 11 to 13 to increase the porosity of said hydrogel-forming polymers in the wet state.
15. A water-swellable material that comprises hydrogel forming polymers, which are coated by a coating formed from a coating agent comprising an elastomeric polymeric material, whereby said coating is present at a level of at least 1% by weight of the water-swellable material, and whereby the water swellable material has a CCRC of at least 10g/g and whereby said coating agent comprises elastomeric polymers that are elastic at 35°C or even at 20°C, selected from the group of reactive, preferably carboxylated, natural rubber, synthetic rubber and thermoplastic elastomers.
