The new cyclic carbonate monomer 2,4,8,10-tetraoxaspiro [5,5]undecane-3one (DOXTC) was prepared in ΓΊ 80% yield by the reaction of 1,3-dioxane-5,5-dimethanol with ethyl chloroformate in tetrahydrofuran (THF). DOXTC homopolymerization and copolymerizations with trimethylene carbonate (TMC) were carrie
