Use of macromonomers as reactive (copolymerizable) surfactants in heterogeneous systems such as emulsion and dispersion constitutes an increasingly important application in the design of polymeric microspheres, as will be discussed later in Sect. 6. Here the macromonomers copolymerize in situ with some of the substrate comonomers to afford the graft copolymers, the grafts (branches) of which serve as effective steric stabilizers by anchoring their backbone onto the surfaces of the particles. In general, however, the copolymerization reactivities of macromonomers in such systems are not well understood yet. 

In view of the foregoing discussion, it is not surprising that many emulsion polymerizations can be carried out without the addition of free surfactants. This is accomplished by use of ionic initiators, like the widely used persulfates, with the additional assistance of copolymerizable surfactants, if these are needed. It should be realized, however, that emulsion polymerization itself generates surfactants, and the process cannot therefore be entirely surfactant free.
