A fluid-absorbing, composite material that is pressure sensitive adhesive an d which is made of a mixture comprising a continuous phase formed from a pressure sensitive adhesive matrix, and a discontinuous phase substantially comprised of one or more natural or synthetically derived water soluble and/ or water insoluble absorbents, characterised in that the continuous phase contains trans-polyoctenamer polymer, which material serves to elevate the shear strength of the composite. Because of its low melting point, compositions containing trans-poyloctenamer polymer are very easy to process . Formulations can be prepared that have only weakly adhesive properties, also formulations that are suitable as primary dressings for various hard-to-heal and chronic wounds. The pressure sensitive adhesive can also be combined wit h a non-adhesive, water impervious film, or other backing material, and can be used as the protective adhesive skin barrier component of ostomy pouches.</S DOAB>
