| Abstract: | Acrylic acid,sodium hydroxide as raw materials and ammonium persulfate as initiator,and sodium bisulfite as chain transfer agent were used to synthesize sodium polyacrylate possessing a low relative viscosity average molecular weight from 2 000 to 4 000.By means of orthogonal experimental method the optimal conditions were acquired: reaction time 2.5 h,reaction temperature 55 ℃,acrylic acid concentration 35%,ammonium persulfate content 4%,sodium bisulfite content 6%. |
| Keywords: | sodium polyacrylate viscosity average molecular weight process conditions scale inhibiting performance solid content |
