Improved understanding of emulsion polymerization has relaxed that criterion to include more than one growing chain per particle, however, the number of growing chains per particle is still considered to be very low.

"Note " : With the exception of " mini-emulsion polymerization ", the term emulsion polymerization does not mean that polymerization occurs in the droplets of a monomer emulsion.
23.
This is important because it fills the gap between particle size generated by conventional emulsion polymerization ( 0.006 0.7 �m ) in batch process and that of suspension polymerization ( 50 1000 �m ).
24.
It is applicable in the areas of free radical and controlled radical homo-and copolymerization, polyelectrolyte synthesis, heterogeneous phase reactions, including emulsion polymerization, adaptation to batch and continuous reactors, and modifications of polymers.
25.
A dispersion resulting from emulsion polymerization is often called a latex ( especially if derived from a synthetic rubber ) or an emulsion ( even though " emulsion " strictly speaking refers to a dispersion of an immiscible liquid in water ).
26.
Other production processes, such as micro-suspension polymerization and emulsion polymerization, produce PVC with smaller particle sizes ( 10 ?m vs . 120 150 ?m for suspension PVC ) with slightly different properties and with somewhat different sets of applications.
27.
While third phase is a term for an unwanted emulsion, a stable emulsion is wanted in emulsion polymerization all the things which can be used to make a stable'emulsion'for a latex synthesis can prove to encourage a third phase to form.
28.
Over the next twenty years, through the end of World War II, efficient methods for production of several forms of synthetic rubber by emulsion polymerization were developed, but relatively few publications in the scientific literature appeared : most disclosures were confined to patents or were kept secret due to wartime needs.
29.
The kinetics of microemulsion polymerization has much in common with emulsion polymerization kinetics, the most characteristic feature of which is the compartmentalization, where the radicals growing inside the particles are separated from each other, thus suppressing termination to a high extent and, as a consequence, providing high rates of polymerization.
