Abstract
The present invention relates to a three-dimensional solid polymeric article having surface effects comprising a polymer composition and 0.1 to 20% by weight of a hydrophobic compound, based on the total weight of the solid polymeric article, where the hydrophobic compound is intermixed throughout the polymer composition and throughout three-dimensional solid polymeric article; and where the hydrophobic compound is selected from a cyclic alcohol which is substituted with at least two hydrophobic groups.
