1. A hydrogen getter composition for removing hydrogen and its isotopes from within an enclosed space, comprising:

  • an organic polymer, said organic polymer further comprising a plurality of repeating monomer units, said units having up to six side branches, said side branches further comprising C1 -C8 alkyl that contain or are substituted with one or more functionalities selected from the group consisting of C2 -C8 alkene, C2 -C8 alkyne, C1 -C8 ether, C1 -C8 alcohol, C1 -C8 ester, phenyl, C1 -C10 anhydride, C1 -C8 isocyanate, C1 -C8 ketone, C1 -C8 epoxide, and C1 -C8 carboxylic acid such that each said unit contains at least one carbon-carbon double bond;

    a hydrogenation cataylst consisting essentially of a noble metal catalyst and an inert catalyst support material, said hydrogenation catalyst distributed throughout said getter composition wherein said double bonds and said noble metal catalyst are in reactive association; and

    an inert diluent, said diluent selected from the list consisting of carbon black powders, mineral powders, salts, thixotropic agents and combinations thereof.
