Abstract
It has now been surprisingly and unexpectedly discovered that a combination of polychlorophenoxyphenol, a silver-containing biocide, and an organopolysiloxane, when added to UHMWPE, renders the UHMWPE resistant to both soft and hard fouling. The polychlorophenoxy phenol is preferably 2.4.4′-trichloro-2′-hydroxy-diphenylether and the metal-containing biocide is preferably a silver zeolite.
