As the result of our research, our team made out the decision to produce the Sodium polycarboxylate polymer dispersant. In the first place, we will use the method of solution polymerization to prepare MPEGAA, and then it will participate in the copolymerization with acrylic acid and odium styrene sulfonate to the Sodium polycarboxylate polymer dispersant. We also depict the development status and development prospects of this dispersant. We believed we made the best choice in each process, including polymerization process, materials, process appliances, as well as operation method. We calculated the material balance and thermal balance; besides we have done calculation on equipment choosing, ba...
