Ion-exchange Resin
An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface area on and inside them where the trapping of ions occurs along with the accompanying release of other ions, and thus the process is called ion exchange. There are multiple types of ion-exchange resin. Most commercial resins are made of polystyrene sulfonate.François Dardel and Thomas V. Arden "Ion Exchangers" in Ullmann's Encyclopedia of Industrial Chemistry, 2008, Wiley-VCH, Weinheim. . Ion-exchange resins are widely used in different separation, purification, and decontamination processes. The most common examples are water softening and water purification. In many cases ion-exchange resins were introduced in such proce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rohm And Haas
Rohm and Haas Company is a manufacturer of specialty chemicals for end use markets such as building and construction, electronic devices, packaging, household and personal care products. Headquartered in Philadelphia, the company is organized into three business groups of Specialty Materials, Performance Materials and Electronic Materials, and also has two stand-alone businesses of Powder Coatings and Salt. Formerly a Fortune 500 Company, Rohm and Haas employs more than 17,000 people in 27 countries, with its last sales revenue reported as an independent company at US$8.9 billion. Dow Chemical Company bought Rohm and Haas for $15 billion in 2009. History The company was founded in Esslingen, Germany, by Dr. Otto Röhm and Mr. Otto Haas in 1907. Haas moved to Philadelphia and began the American side of the business on September 1, 1909, from an office on Front Street, while Otto Röhm remained in Germany to run a company that would eventually become Röhm GmbH.

Synthetic Resins
Synthetic resins are industrially produced resins, typically viscous substances that convert into rigid polymers by the process of curing. In order to undergo curing, resins typically contain reactive end groups, such as acrylates or epoxides. Some synthetic resins have properties similar to natural plant resins, but many do not. Synthetic resins are of several classes. Some are manufactured by esterification of organic compounds. Some are thermosetting plastics in which the term "resin" is loosely applied to the reactant(s), the product, or both. "Resin" may be applied to one of two monomers in a copolymer, the other being called a "hardener", as in epoxy resins. For thermosetting plastics that require only one monomer, the monomer compound is the "resin". For example, liquid methyl methacrylate is often called the "resin" or "casting resin" while in the liquid state, before it polymerizes and "sets". After setting, the resulting poly(methyl methacrylate) (PMMA) is often rename ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
