*Dned product readily soluble in all organic solvents Cyanamid's versatile anionic surfactants exhibit an extremely wide range of useful properties. As a result, they are suitable for use in many polymer systems. Whatever type emulsion is required, one or another of these products can deliver virtually any particle size, from 0.02 micron to 1.0 micron. They are all noted for high compatibility, and cause high conversion and rapid rate of polymerization. Their use will permit custom manufacturing of excellent latices whose properties can be greatly varied through choice of the proper emulsifier. Another feature of these surfactants is that small concentrations are required t o produce a desired emulsion. This means lower cost for the surface active' agent and, obviously, less emulsifier present in the finished latex.
