Abstract

A polymerizable composition comprises at least one ring-strained non-conjugated cyclic olefin, a two-part transition metal-containing catalyst wherein said transition metal is selected from the group consisting of Periodic Groups 6 to 10, said catalyst being air and moisture stable and comprises a transition metal-containing catalyst, provided that the oxidation state of the transition metal is in the range of +3 to 0, and as cocatalyst an organosilane comprising at least one group selected from the group consisting of ##STR1## groups.
