Research Progress of Hydrolyzed Polymaleic Anhydride

Fan Dayong;SINOPEC Beijing Research Institute of Chemical Industry Yanshan Branch;  
Hydrolyzed polymaleic anhydride(HPMA) is an important environmentally friendly water treatment agent with excellent scale resistance, and is widely used in circulating water, sea water desalination, boiler water and cooling water.The research progress of synthesis technology and modification technology of HPMA was introduced.Suggestions for the development of HPMA were raised, including continuously improving the production process, studying the scale resistance mechanism, developing new synthesis methods, strengthening chemical modification or compound modification with other scale and corrosion inhibitors, improving the comprehensive performance of products, reducing the production cost, and expanding the application fields, etc.
