## Abstract Several nickel α‐diimine compounds of the general formula (ArNC(R)C(R)NAr)NiX~2~ (Ar = 2,6‐alkyl substituted Ph, R = H or CH~3~, X = Br or CH^3^) were tested in ethylene polymerization after activation with different co‐catalysts, such as methylaluminoxane, Al(C~2~H~5~)~2~Cl or other
## Abstract A nickel α‐diimine catalyst was used for Grignard metathesis (GRIM) polymerization of 2,5‐dibromo 3‐hexylthiophene and 2‐bromo‐5‐iodo‐3‐hexylthiophene monomers. GRIM polymerization of 2‐bromo‐5‐iodo‐3‐hexylthiophene generated regioregular polymers with molecular weights ranging from 3 0
