Creative Chemistry

A large body of work has been developed by DeSimone and co-workers on the solubility of fluorinated polymers, especially polyfl,l-dihydroper-fluorooctylacrylate) fPFOA), in C02 (Hsiao et al., 1995 Luna-Barcenas et al., 1998). An excellent example of utilizing creative chemistry to design a C02-soluble polymer, PFOA is one of the very few fluoropolymers that dissolves in C02 at modest temperatures and pressures less than 300 bar. The characteristics needed to make a fluoropolymer soluble in C02 can be ascertained from Figure 7.2, which shows the difference in cloud-point curves for polyfvinylidene fluoride) (PDVF), a statistically random copoly-... 

In the meantime, there is a ferment in laboratories all over the world. Scientists are still picking the nucleus of the atom apart and trying to put together the twelve to twenty-one subatomic particles already discovered or predicted, to see how the atom really ticks. Creative chemistry is in the middle of this great adventure, too. And it will continue to be as fruitful in many other areas where chemists are searching for new products which nature in all her lavishness neglected to create. 

Creative chemistry must begin with synthesis. The chemical synthesis of macrocyclic ligands that can function as selective receptors for ions and neutral molecules is a central theme of modern supramolecular chemistry. Indeed the synthesis of these tailored receptors can be a real challenge, but it is also great fun I hope that this book conveys some of the enthusiasm of the authors for their subject. 

Catalytic reagents can sharply decrease costs of both reagents and waste disposal and can increase overall productivity. Catalytic hydrogenation has been a mainstay of the chemical industries for many years [42]. In the past two decades, the use of catalytic reagents for forming carbon-carbon bonds has been a very popular quest, and some extremely creative chemistry has emerged [43]. Discussion on optimizing catalytic reactions may be found in Chapter 9. 

Although Soxhiet is nowadays chiefly remembered for his invention of the apparatus that bears his name, his life and work remain an exemplary case of the application of creative chemistry to the improvement of human health.

I would like to dedicate this book on "High Performance Pol)mers - Polyimides Based - From Chemistry to Applications" to Professor Alexander L vovich Russanov known as Shura, and his team from Institute A. N. Nesmeyanov INFOS, Russian Academy of Science, Moscow. His contribution to pol3heterocyclic pol)mers is immense by the originality of the chemistry developed and also by the novelty brought to the Polyimide family and derivatives. Shura has been for nearly thirty years my cheerful companion and during this period I was impressed not only by his creative chemistry but also by his sense of humor and his optimism. For sure, the scientific community will miss him, his competence and joviality. 

Two approaches currently seem open. The first is directed toward conjugated polymers. Here substituted systems may hold potential. Cyclopol3nnerization is a viable method of synthesis of substituted polyacetylenes. Likewise, chemical modification of polyacetylene itself may have potential. The preparation of polyacetylenes by elimination reactions from precursor polymers needs more attention. The second approach is toward non-conju-gated polymers containing aromatic functionalities little work has been done in this area. Much creative chemistry remains to be explored and it will most likely involve new monomers and polymers. ...

Slosson s Creative Chemistry (III, 1919) was one of the most successful books on chemistry published between World Wars I and II. After its first appearance in 1919, new editions followed in 1920, 1921,1930, and 1938. The last two were revised by Harrison E. Howe, editor of Industrial and Engineering Chemistry. (See pp. 100-101 below.)...
