A method for making bactericidal polymers, and the resulting products, are disclosed. The method is based on the formation of a coating having a covalent bond between a bactericidal agent and a three-dimensional network which is in turn adhered to the base material consisting of a synthetic resin, said bond being achieved by the exposure to energy radiation, e.g. ultraviolet radiation, gamma rays or electron bombardment, of a formulation comprising three essential components, i.e. at least one photoinitiator, at least one cross-linkable oligomer and at least one mono- or multifunctional monomer, as well as various additives conferring specific properties to the end product. Said method is particularly useful for producing medical instruments made of synthetic material, especially probes and catheters, but is also useful in numerous other fields. |
