摘要：Polyacrylate dispersants were synthesized by applying orthogonal array experiment method, among which the affecting factors include chain transfer agents: isopropanol (IPA). dodecyl mercaptan (DDM); initiators: benzoylperoxide(BPO), azobisisobutyronitrile(AIBN) and their contents, temperature, the content of acrylic acid and types of the monomers of solvation chains, of which poly (methacrylate), poly (ethyl acrylate), poly (butyl acrylate) were solvation chains. The optimal factors were obtained by comparing the viscosity decrease of the unsaturated polyester resin (UPR)/aluminum hydroxide (ATH) composites with different dispersants, and it showed that the dispersant with poly(butyl acrylate) as solvation chain whose length is around 7.0nm has the best result of improving rheological properties of UPR/ATH Composites and reducing system's thixotropy.
