- (a) at least one monomer unit;
- and
- (b) at least one surface active agent unit,
- wherein
- the monomer unit is derived from an ethylenically unsaturated monomer;
- the surface active agent unit is derived from a polymerizable antibacterial quaternary ammonium compound;
- and
- the ethylenically unsaturated monomer and the polymerizable antibacterial quaternary ammonium compound have reacted to form polymer particles.
