Abstract (en)
[origin: DE19907999A1] According to the invention, monolefins comprising 2 to 12 C atoms can be polymerized to form polymers or copolymers. Said monolefins are polymerized alone or in a mixture as well as with polar monomers such as methylacrylate in the presence of a palladium complex of formula [L1 Pd L2]<+>An<-> and optionally while adding an alkylaluminum compound. In the Pd complex, L1 represents a neutral bidentate N, N'-disubstituted diazadiene ligand, preferably a diazabutadiene ligand; L2 represents an alkoxycycloalkene carbanion with 7 to 8 C annular atoms, preferably a 1-methoxy-cycloocta-4-ene-8 sigma , 4 pi ligand, which is bound to the palladium atom via a sigma bond and whose C=C double bond forms a complexing pi bond to the palladium atom and; An<-> represents an anion of an acid which is non-esterfiable or slightly esterfiable and which is non-coordinating or slightly coordinating. The invention also relates to novel Pd complex catalysts provided for polymerization and copolymerization.
