## Abstract Ringβopening copolymerization of maleic anhydride (MA) with propylene oxide (PO) was successfully carried out by using doubleβmetal cyanide (DMC) based on Zn~3~[Co(CN)~6~]~2~. The characteristics of the copolymerization are presented and discussed in this article. The structure of the c
## Abstract Highly active CaCl~2~βmodified ZnβCo(III) DMCs were prepared. XRD results showed that the modified catalyst CaβDMC containing 0.14βwt.β% CaCl~2~ was amorphous. A higher polymer yield (>61βkg polymer/g catalyst) and a shorter induction period for ROP of PO were observed for CaβDMC than f
