  • DUAL CURE SYSTEM FOR THE CHEMICAL FASTENING OF AN ANCHORING MEANS IN A BOREHOLE
    Publication number: 20230416591
    Abstract: A two-component system can be used for the chemical fastening of an anchor in a borehole by dual cure curing. The dual cure curing used is a combination of radical polymerization and ring-opening olefin metathesis polymerization (ROMP).

  • Method for preparation of ruthenium-based metathesis catalysts with chelating alkylidene ligands
    Patent number: 9562116
    Abstract: The invention relates to a method for preparation of ruthenium-based carbene catalysts with a chelating alkylidene ligand (“Hoveyda-type catalysts”) by reacting a penta coordinated ruthenium (II)-alkylidene complex of the type (L) (Py)X1X2Ru(alkylidene) with a suitable olefin derivative in a cross metathesis reaction. The method delivers high yields and is conducted preferably in aromatic hydrocarbon solvents. The use of phosphine-containing Ru carbene complexes as starting materials can be avoided. Catalyst products with high purity, particularly with low Cu content, can be obtained.
