• Hetero-bimetallic-Salen complex
• Altemating polyester
• Poly(ester-co-ether)
• CHO and MA
• Bulk solvent-free copolymerization

For the hetero-bimetallic complex [Zn(L)(mu(1)-OAc)Yb(mu(1)-OAc)(mu(2)-OAc)(H2O)] (1; H2L = N,N'-bis(3-methoxy-salicylidene)cyclohexane-1,2-diamine), its character of self-owned normal OAc- initiators around two active species endows effective bulk solvent-free copolymerization of CHO (cyclohexene oxide) and MA (maleic anhydride) in the presence of cocatalyst (DMAP, 4-(dimethylamino)-pyridine or TPP, triphenylphosphine) or not. Especially from TPP-assisted controllable copolymerization, perfectly alternating polyesters are obtained.
