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. 

Furthermore, a polycarboxybetaine with a peptide main chain was synthesized from poly(methyl L-glutamate) [57]. Several zwitterionic monomers based on isobutylene with long alkyl spacers between the polymerizable group and the zwitterionic moiety exhibit surfactant properties. They do not undergo free radical homopolymerization, but are copolymerizable with other monomers [58].

Since the presence of a low molecular weight surfactant can reduce the properties of films prepared by these latexes, copolymerizable surfactants (known as surfmers = surfactant + monomer) were investigated for different polymerization systems. For some step-growth polymerizations in inverse miniemulsion, the surfactant is incorporated in the particle, owing to the nature of the functional end groups. Because there is usually only one reactive group in the surfactant, the reaction with the surfactant is detrimental to the molecular weight of the... 

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. 

The fumarates polymerize much more readily than the maleates, since the transition state involving maleates is less resonance stabilized due to noncoplanarity of the carboxyl groups. Derivatives of dialkyl maleates and fumarates have also received attention as copolymerizable surfactants. Significant attention has been given to the polymerization properties of alkyl allyl maleates, diallyl maleates, and...
