ChemCatChem, Volume 18, Issue 13, 14 July 2026.Highly active aluminum catalysts for the ring‐opening copolymerization of LO and PA able to produce syndiotactic alternating copolyester within 3 h are presented. The role of DMAP as cocatalysts for the copolymerization is key and is involved in the opening of the anhydride, however, it blocks the catalytic activity for the LO ROP.
