Ethylene is homopolymerized in the presence of a catalyst consisting essentially of a Group 3 metal complex, preferably a scandium complex, having a bridged ligand structure. Optionally polymer blends are prepared by combining the process with another polymerization process, either in series or in parallel.
L'invention porte sur une homopolymérisation d'éthylène en présence d'un catalyseur principalement composé d'un complexe métallique du groupe 3, de préférence un complexe de scandium à structure pontée de ligand. On peut éventuellement obtenir des mélanges de polymères en combinant ce procédé avec une autre méthode de polymérisation, soit en série, soit en parallèle.
