The present invention relates to novel Ruthenium-based complex compounds which represent viable catalysts, in particular for all sorts of metathesis reactions. Such complex compounds can be prepared by a novel, very favorable and cost efficient method which includes the introduction of an alkylidene ligand into the complex by using vinyl sulfides or vinyl ethers.

The invention relates to a hydrocarbon polymer comprising two exo-vinylene cyclic carbonate terminal groups, of formula (1), production method thereof and use of same for the production of coating, mastic and adhesive compositions.

Cis and trans ruthenium complexes that can be used as catalysts for ring opening metathesis polymerisation (ROMP) are described. The complexes are generally square pyramidal in nature, having two anionic ligands X. Corresponding cationic complexes where one or both of the anionic ligands X are replaced by a non-co-ordinating anionic ligand are also described. Polymers such as polydicyclopentadiene (PDCPD) can be prepared using the catalysts.
