Zusammenfassung:	Anti-blocking polymer compositions comprise at least one ethylene/a-olefÊninterpolymer and at least one anti-blocking agent comprising an amide. The ethylene/a-olefÊn interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. The anti-blocking agent can be erucamide or other amides. The anti blocking polymer composition has a pellet blocking strength of equal to or less than (100) lbs/ft2 (4800 Pa). When the anti-blocking polymer composition is made into a film, the film has a blocking force of less than about (100) grams, measured according to ASTM method (D-3354). L'invention concerne des compositions de polymères anti-adhérents comprenant au moins un interpolymère d'éthylène/a-oléfine et au moins un agent anti-adhérent contenant un amide. Les interpolymères d'éthylène/a-oléfine sont des copolymères multiblocs contenant au moins un bloc mou et au moins un bloc dur. L'agent anti-adhérent peut consister en de l'érucamide ou d'autres amides. La composition de polymères anti-adhérente possédant une force de blocage de granule égale ou inférieure à (100) lbs/ft2 (4800 Pa). Lorsque la composition de polymères anti-adhérente est fabriquée en un film, ce film possède une force de blocage inférieure à environ (100) grammes, mesurée selon le procédé ASTM (D-3354).
