摘　　要：The paper confirms the ratio of chain segment of polyasparticacid and calcium hydroxide molar cover 1:5 and the 2—hour reaction in aqueous solution at the room temperature is the best condition for synthesis of calcium polyaspartate.The calcium polyaspartate was puriffied by the means of calcium polyaspartate were marked with IR spectrum,elemental analysis,molecular weight distribution and degree ionization.The paper confirms the ratio of chain segment of polyasparticacid and calcium hydroxide molar cover 1：5 and the 2-hour reaction in aqueous solution at the room temperature is the best condition for synthesis of calcium polyaspartate.
