International Classification:

A61F 13/15
C08F 4/04
C08F 30/08
C08F 118/02

US Classification:

604366, 604375, 604368, 604367, 5262181, 526319, 526279

Abstract:

The present invention provides a translucent absorbent composite having a substrate with a light transmittance of at least about 60% and a flexible superabsorbent binder polymer composition applied to the substrate. The polymer composition may be prepared from the reaction product of a monomer solution including at least 15% by mass monoethylenically unsaturated monomer selected from carboxylic acid, carboxylic acid salts, sulphonic acid, sulphonic acid salts, phosphoric acid, or phosphoric acid salts; an acrylate or methacrylate ester that contains an alkoxysilane functionality; a copolymerizable hydrophilic glycol containing an ester monomer; an initiator system; and a neutralizing agent. The unsaturated monomer is neutralized to at least 25 mol % and the flexible superabsorbent binder polymer composition has a residual monoethylenically unsaturated monomer content of less than about 1000 ppm. The absorbent composite has a light transmittance of at least 45%.

International Classification:

A61F 13/15

US Classification:

604366000, 604368000

Abstract:

An absorbent article comprises a backsheet and an absorbent layer, where the absorbent layer comprises a flexible superabsorbent binder polymer composition positioned adjacent to the backsheet. The absorbent layer may additionally include a substrate, and the article may additionally include a topsheet. The flexible superabsorbent binder polymer composition may be made from the reaction product of a monomer solution including at least 15% by weight monoethylenically unsaturated monomer, an acrylate or methacrylate ester that contains an alkoxysilane functionality, a copolymerizable hydrophilic glycol containing an ester monomer, an initiator system, and a neutralizing agent. The result is an absorbent article which exhibits improved performance as well as greater comfort and confidence among the user.

International Classification:

A61F 13/15

US Classification:

604368000, 604366000

Abstract:

An absorbent article comprises a topsheet, a backsheet which may be joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. Additionally, the absorbent core comprises at least a superabsorbent polymer material comprising from about 55 to about 99.9% by weight of polymerizable unsaturated acid group containing monomer, and from about 0.001 to about 5% by weight of internal crosslinking agent which are polymerized and prepared into superabsorbent polymer particles and which further include surface additives. The superabsorbent polymer material can also have a degree of neutralization of greater than about 25%. The result is an absorbent article which exhibits improved performance as well as greater comfort and confidence among the user.
