Abstract: Imidazoles are prepared by reacting 2-imidazolines at from 250 DEG to 500 DEG C. in the presence of molybdenum oxide and nickel oxide and/or cobalt oxide and aluminum oxide, silicon dioxide and/or silicates as catalysts. The imidazoles obtainable by the process according to the invention are valuable starting materials for the preparation of dyes, crop protection agents, textile auxiliaries, catalysts for polyurethanes and epoxy resins, surfactants and drugs, for example the corresponding nitroimidazoles.

Abstract: A process for the manufacture of polymers of cycloolefins by ring-opening polymerization of cycloolefins using a catalyst system which consists of (1) a transition metal salt, (2) an organometallic compound of an element in group IVa and (3) an aluminum halide, provided that, per mole of catalyst component (1), there are present from 0.1 to 100 moles of catalyst component (2) and from 0.1 to 250 moles of catalyst component (3). This process makes it possible to manufacutre polymers of cycloolefins in a particularly advantageous manner.
