Abstract (en)

[origin: DE19712378A1] The invention relates to the use of amphiphiles for permanent improvement of colorant compatibility 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 mixturte is subjected as is usual to temperature ranging from 180 to 320 DEG C for form processing such as extrusion, calendering, injection molding and the like.
