Latex emulsion polymerization

Research on the modelling, optimization and control of emulsion polymerization (latex) reactors and processes has been expanding rapidly as the chemistry and physics of these systems become better understood, and as the demand for new and improved latex products increases. The objectives are usually to optimize production rates and/or to control product quality variables such as polymer particle size distribution (PSD), particle morphology, copolymer composition, molecular weights (MW s), long chain branching (LCB), crosslinking frequency and gel content.

The word latex has become a generic term that applies to all kinds of polymer colloidal dispersions, including those found in nature and those obtained by emulsion polymerization. Latex obtained from the sap of certain trees was used around 1600 BC by the Mayas in the ancient Mesoamerica for medicines, paints, manufacturing of rubber balls, waterproof cloths, and other mbber artifacts [1]. At present, there are a vast number of applications of polymer latexes, some of which are mentioned below. The growing variety of applications and environmental concerns has constituted the driving force for the development of this fleld. [Pg.295]

Until the mid-1950 s, vinyl acetate was a moderate volume product used to produce specialty polyolefins, such as cling films. However, in the 1950 s, emulsion polymerization ("latex") began to emerge as a major new product line in the chemical industry. (Emulsion polymerization uses surfactants to generate water based emulsions of polyolefin polymers. These products are most familiar to the consumer as water borne paints, but are also found in a wide variety of... [Pg.375]

Latex la- teks [NS latic. latex, from L. fluid] (1835) (pi lattices or latexes) n. (1) An emulsion of a polymeric substance in an aqueous medium. (2) The sap of the hevea (rubber) tree and other plants, or emulsions prepared from the same. Latices of interest to the coatings and plastics industry are based mainly on styrene-butadiene co-polymers, polystyrene, acrylics, and vinyl polymers and co-polymers. (3) Fine dispersion of rubber or resin, natural or synthetic, in water the synthetic is made by emulsion polymerization. Latex and emulsion are often used synonymously in the paint industry. Emulsified monomers once polymerized become solids or plasticized gel particles and not emulsions but aqueous suspensions.
