Chemistry of Ion Exchange Polymers By far the most common chemistry for ion exchange polymers is based on styrene. The monomer and the polymer polystyrene are shown in the figure. It is possible to introduce functional groups after the polymer is formed, or styrene derivatives with the appropriate functional groups can be copolymerized with styrene. Very seldom is a simple linear polymer used because it is too oily and it changes dimensions markedly as one ion exchanges for another. Almost all ion exchange resins have some degree of crosslinking that comes from adding divinyl benzene to the reaction mixture. The vinyl groups participate in different chains and link them together as shown. Typical crosslinking is from 0.5 to 15 per cent as determined by the proportions of styrene and divinyl benzene. The above figure is somewhat misleading, and the next Java applet may clarify things. Use the choice box to try different amounts of divinyl benzene, but do each one several times to get reasonable statistics. Note that there is not very much divinyl benzene. Note also that this applet does not complete the crosslinking and merely shows in red where there is potential for crosslinking. Having the benzene rings above and below the line of CH groups is better than having them lined up as in the first sketch, but the single bonds to a carbon atom are free to rotate and put the polymer into three dimensions.

Home Staff Research Undergraduate Info ... MRIC The groups at Bangor work mainly in the polymer area, though our colleagues at the affiliated MRCI at NEWI have extensive experience with colloid chemistry. Close collaborations within the department have resulted in the preparation of several new low band gap conducting polymers with potential applications in the electronics industry. New water soluble polymers and fibers are also being developed to provide new, safe materials for medical applications and packaging for foods. Natural polymers are studied and exploited in the universitie's Biocomposites centre . Here the focus is on the interactions and modifcations of polysaccharides, with practical applications such as dying processes and biodegradability at the fore.

Success Factors for Careers in Polymers and Chemistry in our Dynamic Environment Robert S. Moore Background Dr. Robert Moore addressing the luncheon attendees. Photo courtesy of Janet Bryant. Notes from the Discussions, "The Success Factors": Each individual must define success: technical, personal, and financial, and must recognize their own individual strengths and areas to which they can contribute to the overall/group effort. They must deliver on their promises, but be able to say "No" to an overload by knowing their limitations. Strong abilities are essential in spoken and written communication, teamwork, business practices, and leadership, most of which are not usually taught at a university. In an industrial setting these skills are critical, whereas in an academic environment, technical skills predominate. Chemical engineering students are taught more teamwork, whereas academics tend to view each other as competitors. In Industry, teamwork and the associated environment are the norm. Be goal oriented - use "stubbornness", tenacity, and pragmatism in driving toward your goal, but also identify new opportunities or create them if necessary.

Polymer Chemistry Glossary Absorption Not to be confused with adsorption absorption is one substance is taken up into the interior of another - adsorption with a 'd' is entirely a surface effect. Examples are the swelling of a poly(acrylamide) polymer with aqueous solution (in a disposable nappy) or the dissolution of carbon dioxide in seawater (one of the possible antidotes to global warming that crops up in models of world climate. Entry: 155 Acetaldehyde Oops, I should have used the systematic name, ethanal ! This is a good example of a case where the IUPAC system may be logical, but can easily engender no end of confusion. Ethanol and ethanal are very differnt: Entry: 101 Acid There are three definitions - Arrhenius, Bronsted, and Lewis Acids . In the Lewis conception, which is the most general and useful, an acid is essentially any compound that needs electrons, and a base is basically any compound that wants to give them away. Entry: Acid anhydride Take two carboxylic acid molecules - for example, salicylic acid - and remove water to give a molecule containing a -(C=O)-O-(C=O)- link - this molecule will be an acid anhydride . For example: ethanoic anhydride: ethanoic anhydride (a.k.a acetic anhydride)
