## Abstract Ringβopening metathesis polymerization (ROMP) of norbornene catalyzed by niobium(V) __N__,__N__βdialkylcarbamates Nb(O~2~CNR~2~)~5~, __R__β=βEt (**1**), Me (**2**) was studied in the presence of methylaluminoxane (MAO) as a cocatalyst. These novel catalytic systems resulted very active
Optimized ring-opening metathesis polymerization (ROMP) conditions for cyclohexenyl norbornene (CHNB) have been determined. ROMP of CHNB was carried out with ruthenium trichloride hydrate and ruthenium benzylidene catalysts. The effects of mol % catalyst, type of catalyst, use of a dissolution aid (
