description A method for the improvement of the barrier properties of ethylene homo- or copolymer compositions against permeation of hydrocarbons comprised in liquid fuels or mineral oils is disclosed. The ethylene homo- or copolymer comprises at least one sterically hindered amine compound in an amount of from 100 to 10 000 ppm, calculated on total weight of the polymer. At least one surface of a hollow body made of said ethylene homo- or copolymer is subjected to fluorination.
