Uniform polymer beads of micrometer size

Abstract

Various methods are reviewed that have been developed in recent years to produce uniform polymer beads with diameter larger than 1 pm. Methods such as emulsifier-free emulsion polymerization, suspension polymerization (including non-standard polymerization devices and a method of activated swelling), dispersion polymerization, precipitation polymerization, and other techniques are covered. The discussion focuses on the mechanism of bead formation and variables influencing the properties of the beads. Potential applications of monosized beads in both industry and research are described.

Fluorescent organosilica micro- and nanoparticles with controllable size

“…Instead, the suggested particle formation process is based on a rapid coagulation process preceded by a short nucleation period. This could also explain the narrow size distribution of the MPTMS organosilica particles [41,42].…”

Block Copolymers in Emulsion and Dispersion Polymerization

“…[4] Very systematic and detailed studies have also been reported by Taylor and Dawkins, [193] Horák, [194] and Croucher and Winnik. [195] Without going into details of the kinetics and thermodynamics of this polymerization process, which has been reviewed by the previously mentioned authors, in the following we intend to provide some more recent examples of NAD prepared in the presence of block copolymers as a stabilizer either by free radical or ionic polymerization as well as by polycondensation reactions.…”
