Abstract
A process for the immobilization of a linear polymer, in particular a polyionenes, which is soluble in an aqueous solvent, on a chemically inert carrier material and a matrix having an antimicrobial effect are provided, which are suitable for, in particularly intracorporeally applied, medical appliances and in the form of microporous membranes as filters for water purification or, in the form of beads, as a surface disinfectant. The process is characterized in that the two terminal reactive groups of the linear polymer are reacted with an excess of an alpha, omega-bifunctional compound, the reaction product obtained is dissolved in a hydrophilic solvent and applied at least once to the carrier material and then cross-linked with a cross-linking agent dissolved in a hydrophobic solvent which is chemically inert to the cross-linking agent and the carrier material.
