Fundamentals of Emulsion Polymerization Biomacromolecules

The first successful theory to explain the distinct features of emulsion polymerization was developed by Smith and Ewart, and Harkins in the 1940s, based on their studies of polystyrene. Smith and Ewart arbitrarily divided the mechanism of emulsion polymerization into three stages or intervals. Subsequently, it has been recognized that not all monomers or systems under… Web4.4.2.2 Polymer systems for latex resins. The following is a discussion of various polymer systems used in latex emulsion resins. 4.4.2.2.1 Poly(vinyl acetate) Poly(vinyl acetate) (PVAc) latex emulsions are common and low cost.
