A novel strategy to combine polymerizable surfactant properties and N-halamine chlorine modulated antimicrobial performance in a single monomer is explored. Thanks to their amphiphilic structure and in a manner similar to the non-polymerizable analogues, polymerizable surfactants play a crucial role in providing colloidal stability when used in emulsion polymerization. In this report, a family of novel cationic polymerizable surfactants, with unique structural attributes will be presented. Once co-polymerized, these positively charged surfactants impart N-halamine functionality to the polymer backbone, which can subsequently provide antimicrobial properties to the binder after film formation, and upon treatment with a dilute bleach solution. The polymerizable surfactants are introduced into a typical Styrene-Acrylic formulation, and the prepared binder is characterized and compared against a control.
