A novel process is disclosed for the continuous process for making a vinyl acetate/acrylamido copolymer product, employing vinyl alcohol and 2-acrylamido-2-methyl propane sulfonic acid or a salt of such acid (AMPS). The process generally includes feeding with agitation, vinyl acetate and AMPS as a comonomer, a polymerization initiator, and a solvent so as to produce the desired product. |
