Beschreibung
Zusammenfassung:	The present invention is directed to a polymer composition comprising a bi- or multimodal ethylene polymer (P) and a nucleating agent being a dicarboxylic acid of a cyclic alkane. Further, the presentinvention is directed to an article comprising said polymer composition and the use of a nucleating agent being a dicarboxylic acid of a cyclic alkane to decrease the water vapour transmission rate and oxygen transmission rate of a polyethylene film. 本发明涉及一种聚合物组合物，其包含双峰或多峰乙烯聚合物(P)和成核剂，所述成核剂是环状烷烃的二羧酸。此外，本发明涉及一种包含所述聚合物组合物的制品以及成核剂用于降低聚乙烯薄膜的水蒸气透过率和氧气透过率的用途，所述成核剂是环状烷烃的二羧酸。
