Latest Patents

Shuying Zhai holds a patent for the "Preparation method for polycarboxylate water reducer having regular sequence structure." This patent discloses a method that involves performing Michael addition on polyethylene glycol ether acrylate macromonomer A and amino-containing carboxylic acid B for 5-12 hours. The process includes cooling to 0°C, followed by a slow and even dropwise addition of acryloyl chloride, and further reacting for 12 hours at room temperature. The result is a carboxyl-containing polyether macromonomer C, which is then mixed with a small molecular RAFT reagent, an initiator, and water. The polymerization is conducted at a mass concentration of 30%-60% and heated to 60-80°C in a nitrogen atmosphere for 2-5 hours to obtain the desired polycarboxylate water reducer.
