Polyaddition of bifunctional spiro orthoesters (SOEs) with bifunctional acid chlorides was examined to develop zero-shrinkage polymerization. The polyaddition afforded the corresponding polyether-esters by repeating the addition reaction accompanying the double ring-opening isomerization of the SOE
