PCT No. PCT/EP95/04866 Sec. 371 Date Jul. 9, 1997 Sec. 102(e) Date Jul. 9, 1997 PCT Filed Dec. 11, 1995 PCT Pub. No. WO96/19540 PCT Pub. Date Jun. 27, 1996Compositions comprising at least one nonvolatile acetylene alone or together with a strained cycloolefin and catalytic amounts of a catalyst for metathesis polymerization, which comprise at least one one-component catalyst from the group molybdenum compounds, tungsten compounds, niobium compounds and tantalum compounds which comprise (a) either at least two methyl groups or two monosubstituted methyl groups without alpha hydrogen atoms in the substituent or (b) at least one halogen and only one silylmethyl group attached to the metal. The storage-stable compositions can be polymerized by the action of actinic radiation or by short-term irradiation and subsequent thermal curing. The polymers can be used to prepare shaped articles, films, coatings and relief images. |
