Abstract (en)

[origin: WO0136503A1] Ethylene, dienes and optionally alpha -olefins are copolymerized by selected iron complexes of 2,6-pyridinecarboxaldehydebis(imines) and 2,6-diacylpyridinebis(imines). The resulting copolymers contain residual olefinic unsaturation from the diene monomers, and some of these copolymers contain cyclic units in the main chain.
