Water unstable bioadhesive compositions comprising an aqueous plasticiser, a cross-linking agent, a copolymer of a hydrophilic unsaturated water soluble firt monomer a hydrophobic unsaturated water-soluble second monomer, characterised in that they have: (i) a water activity of from 0.4 to 0.9; (ii) an elastic modulus at 1 rad/s of from 700 to 15,000 Pa; (iii) an elastic modulus at 100 rad/s of from 20000 to 40,000 Pa; (iv) a viscous modulus at 1 rad/s of from 400 to 14,000 PA; (v) a viscous modulus at 100 rad/s of from 1000 to 35,000 Pa; wherein the viscous modulus is less than the elastic modulus in frequency range of from 1 to 100 rad/s; amd wound dressings made from them.
