Described herein are absorbent articles made by bonding a copolymer onto a substrate to form a core. The absorbent articles are particularly useful in personal care product, e.g., disposable hygiene products. In some embodiments, the absorbent article includes a first substrate； and a copolymer irreversibly bonded onto the first substrate to form a core, wherein the copolymer is derived from a polymerizable solution comprising: (a) a first monomer selected from a (meth)acrylic acid or salt thereof； (b) greater than 1 wt % of a second monomer, wherein the second monomer is a hydrophilic crosslinking monomer, and (c) a polymeric porogen.L'invention concerne des articles absorbants et des procédés de fabrication de tels articles. Lesdits articles sont fabriqués par collage d'un copolymère sur un substrat pour former une partie centrale. Lesdits articles absorbants sont particulièrement utiles dans des produits de soins personnels, par exemple des produits d'hygiène jetables.
