Polyaddition of bifunctional bicyclo ortho esters (BOEs) with bifunctional acid chlorides were carried out to afford quantitatively the corresponding polymers via a double ring‐opening isomerization process. Polyaddition of bifunctional BOEs with a trifunctional acid chloride, 1,3,5‐benzenetricarbonyl chloride, also proceeds satisfactorily to yield crosslinked polymers quantitatively. The mixtures of BOEs and acid chloride show zero to low shrinkage (0.6%) during the polyaddition reaction.
