ABSTRACT:
The present invention provides a wound treating agent in powder form based on a swellable organic polymer, which comprises a cross-linked polymer of a hydrophilic acrylic or methacrylic acid derivative, which polymer is permeated by a gellable polysaccharide and/or protein or polypeptide, the agent being obtainable by polymerizing a hydrophilic acrylic or methacrylic acid derivative in the presence of a dissolved, gellable polysaccharide and/or protein or polypeptide and of a cross-linking agent.
The present invention also provides a process for the production of this wound treating agent, wherein a hydrophilic acrylic or methacrylic acid derivative is polymerized in an aqueous solution of a gellable polysaccharide and/or protein or polypeptide in the presence of a cross-linking agent and of a conventional polymerization initiator, to give a transparent gel which is dried and pulverized.
