Ethylene polymer, has a high resistance to thermo-oxidative degradation in the presence of liquid fuels, INCLUDING BIODIESEL AND OXYGEN AND PLASTIC FUEL TANK MADE OF SUCH POLYMER

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to use of a stabilised composition based on an ethylene homo- or copolymer containing a combination of at least two sterically hindered amine compounds for making plastic articles for transportation and storage of esters of vegetable oil, preferably plastic fuel tanks for motor vehicles, including single-layer or multi-layer articles. At least one of the sterically hindered amine compounds is selected from compounds having the chemical formula: ;and a chemical formula: ;, where n is an integer ranging from 2 to 20. The invention also describes a plastic article and components for transportation and storage of liquid fuels, including biodiesel fuel.;EFFECT: high resistance to thermal oxidative decomposition caused by presence of liquid fuels, such as biodiesel fuel, including esters of vegetable oils, together with oxygen.;7 cl, 3 tbl, 7 ex
