Ethylene may be polymerized by contacting it with certain iron or cobalt complexes of selected 2,6-pyridinecarboxaldehydebis(imines) and 2,6-diacylpyridinebis(imines). The polymers produced are useful as molding resins. Novel 2,6-pyridinecarboxaldehydebis(imines) and 2,6-diacylpyridinebis(imines), and novel complexes of 2,6- pyridinecarboxaldehydebis(imines) and 2,6-diacylpyridinebis(imines) with iron and cobalt are also disclosed.
L'éthylène peut être polymérisé par mise en contact avec certains complexes, contenant du fer ou du cobalt, de 2,6-pyridinecarboxaldéhydebis(imines) et 2,6-diacylpyridinebis(imines) sélectionnées. Les polymères produits sont utilisés en tant que résines à mouler. La présente invention concerne également de nouvelles 2,6-pyridinecarboxaldéhydebis(imines) et 2,6-diacylpyridinebis(imines), et de nouveaux complexes de 2,6-pyridinecarboxaldéhydebis(imines) et de 2,6-diacylpyridinebis(imines) contenant du fer et du cobalt.
