HYDROGEN GETTER COMPOSITION

摘要

The present invention relates to a composition capable of hydrogen sorption in a closed container at low pressure, comprising an usaturated organic substance and a hydrogenation catalyst. Said unsaturated organic substance is a compound having general formula (A) or (A'), or a dimer or polymer thereof, or a copolymer wherein one of the structural units has the general formula (A) or (A'): wherein R<1>, R<2> and R<3> are hydrogen or hydrocarbon moieties optionally comprising one or more heteroatoms, at least one among R<1>, R<2> and R<3> being chosen in the group of alkenyl, alkynyl, arylalkenyl and arylalkynyl moieties, optionally comprising one or more heteroatoms.
