| Abstract: | A acrylic terpolymer was synthesized with potassium persulphate as inititor,acrylic acid,methacrylic,2-acrylamido-2-methyl propanesulfonicacid as monomers.The weight-average molecular weight (M_w) of the terpolymer synthesized in different inititor concentration was determined by the gel permeation chromatography(GPC) after the terpolymer has been dialysed.The intrinsic viscosity \ was determined with ubblohde viscometer, the Mark- Houwink constants were calculated by the Mark- Houwink equation and the result was k= 6.74 × 10 ~(-3) ,α= 0.87. |
