A series of long‐chain quaternary ammonium halogen esters (UKK‐chemicals), quaternary dimethyl tallow epoxypropyl ammonium halogens (EPK1), quaternary ditallow methyl epoxypropyl ammonium halogens (EPK2), and EPK2 oligomers (EPK2P) were synthesized. At acidic, neutral, or slightly basic conditions, EPK1‐, EPK2‐, EPK2P‐, and UKK‐chemicals operate as cationic chemicals. They can be used, for example, as stock sizings, surface sizings, or fixatives. Stock sizing, surface sizing, and fixative experiments indicate that EPK1‐, EPK2‐, EPK2P‐, and UKK‐chemicals function at least as well as or better than the corresponding synthetic chemicals used in papermaking.
