METHOD TO IMPROVE THE BARRIER PROPERTIES OF ETHYLENE POLYMER AGAINST PERMEATION OF HYDROCARBONS AND PLASTIC FUEL TANK HAVING IMPROVED BARRIER PROPERTIES

摘要

The present invention relates to a method for improving the barrier properties of ethylene homo-or copolymer compositions for the penetration of hydrocarbons contained in liquid fuels or mineral oils. The ethylene homo-or copolymer contains at least one hindered amine compound in an amount of 100 to 10,000 ppm calculated relative to the total weight of the polymer. At least one side of the hollow body composed of the ethylene homo-or copolymer is fluorinated.
