Studies on the polymerization of acrylic acid by orthogonal experimental design

Redox polymerization of acrylic acid in water solution was studied by means of orthogonal experimental design. Effects of reaction temperature, reaction time, monomer concentration and redox irritator concentration on the polymerization were exdrined. Optimum condition for preparing polyacrylic acid of high viscosity by redox initiation was obtained and sequence of factors effecting on the polymerization was deterndned.
