## Abstract Highly active CaCl~2~‐modified Zn‐Co(III) DMCs were prepared. XRD results showed that the modified catalyst Ca‐DMC containing 0.14 wt.‐% CaCl~2~ was amorphous. A higher polymer yield (>61 kg polymer/g catalyst) and a shorter induction period for ROP of PO were observed for Ca‐DMC than f
