    • For the production of polyalkenamers there are provided catalysts consisting essentially of a catalyst system for the ring-opening polymerization of cyclic olefins consisting essentially of (1) a tungsten or molybdenum compound; (2) an organoaluminum compound; and (3) an ether of vinyl alcohol, of allyl alcohol, or of 2-butene-1,4-diol, the molar ratio of component (1) to component (2) being less than 1 : 1 and the molar ratio of component (1) to component (3) being less than 100 : 1. The catalyst system may also contain a compound containing one or more hydroxyl or sulfhydryl groups in a molar ratio to component (1) of about 0 : 1 to 2 : 1, respectively.
