    • Use of at least one unmodified polyolefin [polyolefin (P1)] as additive for a polyolefin composition (C2) comprising at least one polyolefin modified by grafting with acid and/or anhydride groups, which groups are optionally completely or partially neutralized by a neutralizing agent [polyolefin (P2)], for improving the level of at least one mechanical property of the polyolefin composition (C2) up to a level which is improved both with respect to that of the mechanical property of the polyolefin composition (C2) and with respect to that of the mechanical property of a polyolefin composition (C1) obtained by replacing, weight for weight in the polyolefin composition (C2), all the modified polyolefin (P2) by the unmodified polyolefin (P1). Use of at least one polyolefin modified by grafting with acid and/or anhydride groups, which groups are optionally completely or partially neutralized by at least one neutralizing agent [polyolefin (P2)], as additive for a polyolefin composition (C1) comprising at least one unmodified polyolefin [polyolefin (P1)] for improving the level of at least one mechanical property of the polyolefin composition (C1) up to a level which is improved both with respect to that of the mechanical property of the polyolefin composition (C1) and with respect to that of the mechanical property of a polyolefin composition (C2) obtained by replacing, weight for weight in the polyolefin composition (C1), all the unmodified polyolefin (P1) by the modified polyolefin (P2).
    • 使用至少一种未改性的聚烯烃[聚烯烃(P1)]作为聚烯烃组合物(C2)的添加剂,其包含至少一种通过与酸和/或酸酐基团接枝而改性的聚烯烃,该基团任选地被中和剂完全或部分中和 [聚烯烃(P2)],用于将聚烯烃组合物(C2)的至少一种机械性能的水平提高至相对于聚烯烃组合物(C2)的机械性能改善的水平,并且相对于 通过用未改性的聚烯烃(P1)代替聚烯烃组合物(C2)中的重量,所有改性聚烯烃(P2)得到的聚烯烃组合物(C1)的机械性能。 至少一种通过与酸和/或酸酐基接枝改性的聚烯烃的用途,所述基团任选地被至少一种中和剂[聚烯烃(P2)]完全或部分中和,作为至少包含至少一种聚烯烃组合物 一种未改性的聚烯烃(聚烯烃(P1)],其用于将聚烯烃组合物(C1)的至少一个机械性能的水平提高到相对于聚烯烃组合物(C1)的机械性能和 相对于通过用聚烯烃组合物(C1)代替重量的所有未改性聚烯烃(P1)的改性聚烯烃(P2)获得的聚烯烃组合物(C2)的机械性能。
