This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.

Process for making water-swellable material comprising coated water-swellable polymers

A filter block may comprise activated carbon filter particles without metallic biocides. The activated carbon filter particles may have a median particle size of less than or equal to about 90 microns and having a particle span of less than or equal to about 1.7. The filter block may have a permeability of greater than about 3.0&#xd7;10cmand a Filter Viruses Log Removal of greater than about 2 logs. A portion of the activated carbon filter particles may be coated with a cationic polymer. Another filter block may comprise mesoporous activated carbon filter particles without metallic biocides, wherein the mesoporous activated carbon filter particles may have a median particle size of less than or equal to about 104 &#x3bc;m and a particle span of less than or equal to about 2.05, and wherein at least a portion of the filter particles may be coated with a cationic polymer. The filter block may have a permeability of greater than about 2.0&#xd7;10cmand a Filter Viruses Log Removal of greater than about 2 logs.

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.

This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a wet-elongation of at least 400%, or even more preferably at least 500%, and preferably a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.

A filter block having a permeability of greater than about 3.0*10cm, and a F-VLR of greater than about 99% is provided. The filter block may be made of filter particles having a median particle size of less than about 50 microns and having a particle span of about 1.4 or less. The filter blocks of the present invention can be used to make a filter for filtering liquids and more specifically, for providing potable water. The filter particles may be mesoporous. Kits comprising filters and information relating to the killing or removal of bacteria, viruses, and microbials are also provided.

The present invention relates to the use, for adhesion on hair or fiber-populated surfaces, of hydrogel adhesive characterized by a G', (1 rad/sec) or below 1000 Pa, resulting in embedding of the hair of fiber and good adhesion properties on the surface. The invention also encompasses Personal Care Products and Surface Care Articles containing the hydrogel compositions herein.
