摘要：
A water absorbent water insoluble polymeric element, such as a fibre, film, coating, bonding layer or foam, is made by forming a substantially linear polymer by polymerisation of water soluble ethylenically unsaturated monomer blends comprising carboxylic and hydroxylic monomers and then reacting the carboxylic and hydroxylic monomers in the linear polymer to form internal cross links within the polymer.
