Verwendung von Amphiphilen zur Hydrophilisierung von Polyolefin-basierten Formkörpern, Fasern und Folien

摘要

The invention relates to the use of amphiphiles for permanent hydrophilic treatment of surfaces of polyolefin-based shaped bodies, fibers and films involving the treatment of a mixture containing a) a predominant amount of one or several polyolefins, b) 0.01-10 wt.% - in relation to the polyolefins - of one or several migratable amphiphiles (additive I) and c) between 0.01-1,000 ppm of one or several transition metal compounds (II) - metal content of transition metal compounds (II) in relation to the polyolefins - , wherein said mixture is subjected as is usual to temperatures ranging from 180 to 320 DEG C for form processing such as extrusion, calendering, injection molding and the like.
