Abstract:
1. A hydrogel composition for the treatment of wounds, comprising a hydrophilic copolymer carrying multiple pendant sulphonic groups, wherein the copolymer is derived from a first olefinically unsaturated sulphonic acid monomer and a second olefinically unsaturated sulphonic acid ester monomer, wherein both monomers have an octanol:water partition coefficient (LogP) value of less than 0, wherein the first monomer has a LogP value greater (more positive) than the second monomer, the molar ratio of the first monomer/second monomer in the hydrogel is between 1 to 3, and both the first and second monomers comprise a pendant sulphonic group in salt form and the counterion for both monomers is sodium, and wherein the first monomer is acrylic acid (3-sulphopropyl) ester (NaSPA) and the second monomer is 2-acrylamido-2-methylpropanesulphonic acid (NaAMPS).
