Miniemulsion polymerization of methyl methacrylate with dodecyl mercaptan as cosurfactant

Synthesis of nano-particles by miniemulsion polymerization

“…does not affect the polymerization rate, in contrast to that of HD (see Figure 6.20) the increase of which leads to an increase of the polymerization rate. These observations are in agreement with Mouran [121] who described that the presence of cosurfactant (DDM) does not strongly affect the overall rate, but does decrease the rate per particle. This could be due to higher rates of desorption (due to chain transfer to DDM and subsequent desorption of the resulting low molecular weight radical) or higher rates of termination.…”

Batch and Semibatch Mini/Macroemulsion Copolymerization of Vinyl Acetate and Comonomers

“…The rate of polymerization depends on many factors, such as particle number, free radical number in polymerizing particles, monomer transport from monomer reservoirs to polymerizing sites, etc. For similar recipes, although higher radical numbers can be accommodated by miniemulsion particles, owing to their larger size, a larger number of particles are produced in the macroemulsion. As mentioned in the former section, there may still be a quite fraction of droplets unnucleated in miniemulsion system.…”

Preparation of fluorescent pigment latex and its application on binder‐free printing of cotton fabrics

“…The Δ d between O/W emulsion and FPLD was close to zero with 1.5% HD [Figure (g)]. This result can be attributed to the long alkane chains of HD, which effectively reduced the Ostwald ripening effect . In addition, the FPL also exhibited lower gel rate and relatively high FI with 1.5% HD.…”
