Neutral nickel σ-acetylide complex [Ni(C≡CPh)₂(PBu₃)₂] is a novel initiator for the polymerization of styrene in CHC1₃ over a range of polymerization temperature from 40℃ to 60℃. The polystyrene obtained was a syndio-rich atactic polymer and its weight-average molecular weight reached 279000. The mechanism of the polymerization was discussed and a radical mechanism was proposed.
