Synthesis and size control of polystyrene latices via polymerization in microemulsion

Comparison of glass formation kinetics and segmental relaxation in polymers

“…The molecular weights between crosslinks for the PVE were 7.6, 3.8, 1.5, 1.1, and 0.12 kg/mol (from 140 down to 2 chain units per network chain). The PS lgels, which are crosslinked nanoparticles prepared by polymerization in microemulsion [33,34], all had a total molecular weight equal to ca. 2000 kg/mol, with molecular weights between crosslinks equal to 0.94, 4.1, and 8.2 kg/mol (i.e., 9±79 repeat units per network strand).…”

Surface functionalization of polymer latex particles. II. Catalytic oxidation of poly(methylstyrene) latexes in the presence of cetyltrimethylammonium bromide

“…14 In our system, a 17% PMS emulsion was prepared in the absence of a crosslinker along tant residue and metal salt. repulsion as a result of the acetate anions associLatex Particles ating with the surfactant cations, reducing the charge density on the particle surface.…”

Preparation of 20-nm poly(styrene derivative) particles via polymerization with nonionic surfactant at the phase-inversion temperature

“…Furthermore, the weight ratio of polymer to surfactant is less than one-third. Antonietti et al 3 succeeded in controlling the diameter of the generated polystyrene particles by changing the molar ratio of surfactant to charged monomer. They successfully prepared the particles and the hydrodynamic diameter that was measured by dynamic light scattering (DLS) was as small as 20 nm when using cetyltrimethylammonium bromide.…”
