Zusammenfassung:	The present invention relates to a composition comprising the following: a) at least one ethylene/alpha-olefin multiblock interpolymer comprising soft segments (SS) and hard segments (HS), and wherein the interpolymer has the following properties: i) Melt Index (I2) > = 30 dg/min, ii) the molar ratio of "the alpha-olefin in the SS" to "the alpha-olefin in the HS" > = 18, iii) the weight ratio of the SS to the HS < = 12.0; at least one tackifier and/or at least one oil. 本发明涉及一种组合物，该组合物包含以下物质：a)至少一种乙烯/α-烯烃多嵌段互聚物，其包含软链段(SS)和硬链段(HS)，并且其中该互聚物具有以下性质：i)熔体指数(I2)≥30dg/min，ii)"该SS中的该α-烯烃"与"该HS中的该α-烯烃"的摩尔比≥18，iii)该SS与该HS的重量比≤12.0；至少一种增粘剂和/或至少一种油。
