Addition and ring-opening metathesis polymerizations of new monomers (Me3Si- and Me3Ge-substituted tricyclononene and tricyclononadienes) were carried out on Pd- or Ni-catalyst systems and Grubbs first-generation catalyst, respectively. New addition polymers were obtained with good yields up to 70% and molecular weight (Mw) up to 5.6 × 105. The yields of the first obtained metathesis polymers were higher than 80% and Mw were up to 8.8 × 105. It was shown that the novel addition polymer poly[(3-trimethylgermyl)tricyclononene-7] possesses high gas-transport parameters and solubility-controlled permeation of gaseous hydrocarbons.
