The molecular weight of polyolefins produced using iron or cobalt complexes of 2,6-pyridinecarboxaldehyde diimines or a 2,6-diacylpyridine diimines as polymerization catalysts may be lowered by carrying out the polymerization in the presence of hydrogen.
Pour abaisser la masse moléculaire des polyoléfines produites en utilisant comme catalyseur de polymérisation des complexes de fer ou de cobalt des 2,6-pyridinecarboxaldéhyde-diimines ou des 2,6-diacylpyridine-diimines, on réalise cette polymérisation en présence d'hydrogène.
