    • Disclosed are copolymers including an alkylene carbonate, and a method of preparing the same. The copolymers are represented by Formulas 1 and 2, and they are prepared with terpolymerized lactide or delta-valerolactone, carbon dioxide, and alkylene oxide, in the presence of a catalyst. (wherein, —O—A— is an opened alkylene oxide structure, the alkylene oxide being selected from the group consisting of ethylene oxide, propylene oxide, 1-butene oxide, 1,1-dimethylethylene oxide, cyclopentene oxide, cyclohexene oxide, 1-phenylethylene oxide, 1-vinylethylene oxide, and 1-trifluoromethylethylene oxide; and x and y are independently an integer being equal to or less than 2,000, n is an integer, and n=(z-x-y), wherein z is an integer being equal to or less than 20,000.).
