High molecular weights are developed in emulsion polymerization because the concentration of growing chains within each polymer particle is very low.

Although organic peroxides and hydroperoxides are used in emulsion polymerization, initiators are usually water soluble and partition into the water phase.
13.
Suspension polymerizations affords particles with average diameters of 100 180 ?m, whereas emulsion polymerization gives much smaller particles of average size around 0.2 ?m.
14.
The first " true " emulsion polymerizations, which used a surface-active agent and polymerization initiator, were conducted in the 1920s to polymerize isoprene.
15.
Ironically, synthetic rubber manufacture turned more and more away from emulsion polymerization as new organometallic catalysts were developed that allowed much better control of polymer architecture.
16.
Although use of living free radical processes in emulsion polymerization has been characterized as difficult, all examples of iodine-transfer polymerization have involved emulsion polymerization.

18.
His research in emulsion polymerization and development of a low-temperature " cold process " for producing synthetic rubber were among his most well-known research contributions.
19.
Snyder " et al . " proved the sulfur from a mercaptan modifier did indeed become incorporated into a polymer chain under the conditions of bulk or emulsion polymerization.
20.
Bock focused on emulsion polymerization, which had been already invented in 1912 by Kurt Gottlob ( 1881-1925 ) at Bayer, but had so far yielded no practical application.
