Abstract:
A process for the biocidal finishing of plastic materials selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyacrylate, polymethacrylate, polyethylene terephthalate, unsaturated polyesters, polycarbonate, phenol-formaldehyde resins, epoxy resins and melamine resins, which process comprises addinga) either during the processing of the plastic materials or, b) in the case of plastic materials prepared via a radical polymerisation, already during the polymerisation or during the processing or, c) in the case of duroplasts prepared from a phenol-formaldehyde resin, epoxy resin or a melamine resin, during the crosslinking reaction, a biocidally effective amount of at least one compound selected from the group consisting of 2-methylthio-4-cyclopropylamino-6-(&agr;,&bgr;-dimethylpropylamino)-s-triazine, 2-methylthio-4-cyclopropylamino-6-tert-butylamino-s-triazine, 2-methylthio-4-ethylamino-6-tert-butylamino-s-triazine and 2-methylthio-4-ethylamino-6-(&agr;,&bgr;-dimethylpropylamino)-s-triazine.
