Abstract
The invention comprises a method and apparatus for dispensing a biocide, comprising: a container and a biocide formulation in the container, the biocide formulation comprising: (1) the biocide and a solvent, the biocide comprising a protonated polymer comprising repeating charged units; (2) a total cationic charge density in a range of 0.005 to 0.95 meq/g, at least ten percent of the total cationic charge density from charges of non-quaternary amines of the protonated polymer; (3) an activity coefficient, γ, of a protonated site of the protonated polymer, of greater than 0.7; and (4) a counterion chloride concentration of less than 900 ppm.
Claims19
A method for dispensing a biocide, comprising the steps of:
- packaging contents in a container, said contents comprising said biocide and a solvent, said biocide comprising a protonated polymer comprising repeating charged units, said contents comprising a total cationic charge density in a range of greater than 0.01 to less than 0.05 meq/g, at least ten percent of said total cationic charge density from charges of non-quaternary amines of said protonated polymer;
- and
- dispensing said biocide from said container.
