Absorbent products and their manufacture.

摘要

Water absorbent, water insoluble, cross linked polymer fibre or film can be made by dry extrusion of a solution of a substantially linear polymer formed from a water soluble blend of monoethylenically unsaturated monomers comprising a plasticising monomer, evaporating the solvent and forming polymeric fibre or film plasticised by an external plasticiser, stretching the fibre or film while the external plasticiser remains in the fibre or film, and then cross linking the polymer.
