Beschreibung
Zusammenfassung:	An article (e.g. film, tape or pipe) is described comprising a microstructured surface. The microstructured surface comprises a thermoplastic polymer; and a block copolymer additive comprising a poly(alkylene)oxide block having a molecular weight greater than 250 or 500 g/mole and at least one hydrophobic block. Also described is a method of making such articles. Also described is a triblock copolymer comprising a poly(alkylene oxide) midblock and hydrocarbon end blocks; and compositions comprising a thermoplastic polymer and un to 50 wt. % of the block copolymer.
