    摘要: A one step process for making a dendritic hydrocarbon polymer, e.g., dendritic polyolefin, by metathesis insertion polymerization. The process comprises polymerizing an amount of one or more cyclic olefins and one or more multi-functional (meth)acrylates in the presence of a metathesis catalyst and under conditions sufficient to produce the dendritic hydrocarbon polymer. The one or more multi-functional (meth)acrylates have a functionality of 3 or higher. The dendritic hydrocarbon polymer can be hydrogenated to produce a substantially saturated dendritic hydrocarbon polymer. The hydrogenation can take place in the same reaction vessel as the polymerization, i.e., one pot process.

    摘要: This invention provides metal complexes being useful as catalyst components in metathesis reactions and in reactions involving the transfer of an atom or group to an ethylenically or acetylenically unsaturated compound or another reactive substrate and, with respect to a sub-class thereof, for the polymerisation of α-olefins and optionally conjugated dienes, with high activity at moderate tempera-tures. It also provides methods for obtaining polymers with very narrow molecular weight distribution by means of a living reaction. It also provides methods for making said metal complexes and novel intermediates involved in such methods. It further provides derivatives of said metal complexes which are suitable for covalent bonding to a carrier, the product of such covalent bonding being useful as a supported catalyst for heterogeneous catalytic reactions. It also provides a direct one-step synthesis of pyrrole, furan and thiophene compounds from diallyl compounds.
