## Abstract Copolymers of ethylene (E) with norbornene (N) were synthesized using the catalysts __rac__‐Et(Ind)~2~ZrCl~2~/MAO (1), 90%__rac__/10%__meso__‐Et(4,7‐Me~2~Ind)~2~ZrCl~2~/MAO (2), and __rac__‐H~2~C(3‐__t__‐BuInd)~2~ZrCl~2~/MAO (3). Catalyst activity, molar mass (MM), and copolymer composi
The polymerization of aliphatic disubstituted acetylenes was examined with MoOCl 4 -n-Bu 4 Sn-EtOH (1/1/2) ternary catalyst in anisole at 0 °C. Various linear aliphatic disubstituted acetylenes such as 2-nonyne provided polymers with narrow molecular weight distributions (weight-average molecular we
