The reaction conditions ，i.e ，the amount of carbamide ，the amount of sodium dodecyl sulfate ，coordination temperature on freezing point and viscosity of natural polymer bone glue adhesive material ，were optimized using the response surface method. According to the principle of Box-Behnken，experiments were designed and analyzed using the Desig-Expert (V) software. Freezing point and viscosity were taken as the responses to analyze the significance and interactions of various factors. The optimal synthesis conditions were carbamide of 0.78g，SDS of 0.5
