Relations between substituting degree, brei viscosity and monomer concentration, chloroacetic acid concentration, reaction time and reaction temperature are concluded from experiment results, and pH value, change rules of conductivity of the reaction system are studied. 由实验结果得出了取代度、糊液粘度与单体浓度、***浓度、反应时间、反应温度的关系;对反应体系的pH值、电导率变化规律进行了研究;
