Research progress on the preparation and application of monodisperse cationic polymer latex particles

Abstract: This review is focused on the features, preparation and applications of uniform cationic polymer latex particles, as well as on the formation mechanism of uniform latex particles. Substantial progress in the size and shape control of polymer latex particles has been made using several methods such as dispersion polymerization, conventional emulsion polymerization, surfactant‐free emulsion polymerization and seeded emulsion polymerization. Uniform cationic polymer latex particles have wide applications such as … Show more

“…[10] Cationic latex soap-free emulsion polymerization in the presence of cationic initiator. [11][12][13] It is very difficult to control the particle size distribution of the final latex, even though these researches provide a substantial foundation for controlling particle size distribution and particle morphology.…”

“…Cationic polymer particles have received considerable attention because of their unique properties such as a small size with high specific surface area, good mechanical and chemical stability, low surface tension, cationic surface charge, and also due to application as flocculants in mining, water filtration, and sewage treatment, as antimicrobial agents, and in drug delivery systems [1][2][3][4]. Researchers have devoted their time and efforts to study the physical and chemical properties of cationic polyelectrolytes because of their potential to shed light on the fundamental properties of proteins and nucleic acids [5].…”

“…2 Common methods for preparing positively charged colloids cover dispersion, precipitation, emulsion, multiple swelling and seeded polymerizations from various cationic monomers, such as 2vinylpyridine, 4-vinylpyridine, 2-(diethylamino)ethyl methacrylate, 2-(dimethylamino)ethyl methacrylate (DMAEMA). 3,4 Protonated polymer particles based on DMAEMA possess interesting properties, which endow them with a potential for various applications. Poly [2-(dimethylamino)ethyl methacrylate] (PDMAEMA) is a water-soluble polymer and, due to its positive charge, PDMAEMA and its copolymers are able to form electrostatic complexes with anionic biomacromolecules, such as DNA and RNA, and are oen used for gene delivery.…”
