By far, the greatest attention was devoted to developing the various sunshades. That effort required the skills and ingenuity of a wide assortment of specialists, ranging from pipefitters and seamstresses to space physicists and polymer chemists (who were needed to evaluate the effect of solar radiation on the thin, aluminized...
Ever since Du Pont scientists in the 1930s mixed coal tar, air and water to produce nylon, the wizards of Wilmington, Del., have been searching and researching for another equally profitable synthetic smash. By 1964, Du Pont chemists thought that they had found it: a porous polymer that looked and...
Now a completely absorbable, non-irritating suture material has been developed at Lederle Laboratories' Davis and Geck Division in Pearl River, N.Y. To create the catgut substitute, which is trade-named Dexon, chemists tested 225 synthetic compounds before they hit upon polyglycolic acid, a polymer or long-chain molecule...
* So called because its molecules are believed to be linked in a chemical chain, or polymer.
Polyethylene oxide, the material that eased Highburton's passage, is known to chemists as a long-chain polymer because it consists of lengthy strings of linked molecules. In the water near a ship, the molecular chains act much like an array of thin parallel tubes, allowing water to flow...
