This paper deals with the detailed studies on the copolymerization of styrene with acrylamide and its derivatives in an emulsifier-free aqueous medium. Some characteristics with respect to polymerization behavior and properties of resulting latices are clarified and the polymerization mechanism is discussed. It is shown that polymerization of styrene with acrylamide in an emulsifier-free aqueous medium gave stable latices at the monomer ratio lower than acrylamide/styrene equals 1/1. The polymerization course was divided into three stages in terms of the main polymerization locus. The molecular structure of the derivatives affected the particle size, the amount and composition of the polymer dissolved in water phase, and latex stability.
