A highly active rare earth coordination catalyst composed of neodymium acetylacetonate, dibutylmagnesium, and hexamethylphosphoramide (mole ratio 1:7:14) for the polymerization of N ‐phenylmaleimide (N‐PMI) was developed. The resulting poly(N‐PMI) has high molecular weight ( M̄ n = 9.0 × 10 4 ) and shows excellent thermal stability.
