METHODS FOR PRODUCING VINYLAMINE-CONTAINING POLYMER SOLUTIONS AND VINYLAMINE-CONTAINING POLYMER SOLUTIONS PRODUCED THROUGH THE METHODS

Abstract: methods for producing a vinylamine-containing polymer solution and vinylamine-containing polymer solutions produced through the methods are provided herein. in an embodiment, a method for producing a vinylamine-containing polymer solution includes polymerizing n-vinylcarboxamide monomers and hydrolyzing a resulting intermediate polymer formulation. the method involves determining the amount of unreacted n-vinylcarboxamide monomers in the intermediate polymer formulation, modifying one or more process parameters of the polymerization step accordingly, and repeating the polymerization step with the modified process parameter(s). methods of assessing the amount of unreacted monomers include directly measuring the amount of unreacted monomers in the intermediate, observing the color of the product, measuring the wavelength of the product, or measuring the dynamic viscosity of the product.
