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 up to 50 wt,% of the block copolymer. L'invention concerne un article (par exemple un film, une bande ou un tuyau) qui comporte une surface micro-structurée. La surface micro-structurée comprend un polymère thermoplastique ; un additif de copolymère à blocs comportant un bloc poly(oxyde d'alkylène) ayant un poids moléculaire supérieur à 250 ou 500 g/mole et au moins un bloc hydrophobe. Un procédé de fabrication de tels articles est également décrit. Un copolymère tri-bloc comprenant un bloc intermédiaire poly(oxyde d'alkylène) et des blocs d'extrémité hydrocarbonés est en outre décrit, ainsi que des compositions comprenant un polymère thermoplastique et jusqu'à 50 % en poids du copolymère à blocs.
