I.4.2.I. Synthesis and Modification of Polymers Unstable bis(nitrile oxide), generated by dichloroglyoxime dehydrochlorination, polymerizes in solution to give poly(furoxan) or (in the presence of 1,3-dienes) gives rise to their being cross-linked (500). Polymerization of terephthalonitrile dioxide and its... 

Important for both the synthesis and modification of polymers is also the elongation of polymer chains. Bisnitrile oxides have been claimed as reagents for chain elongation of polyimides containing terminal groups with C=C, C=C, C=N, C=0, and C=N bonds (504). 

We have already seen in this section how ultrasound, like milling, is capable of producing chain scission and thus give rise to macroradicals. It is therefore not surprising that the application of ultrasound to the synthesis and modification of polymers has attracted, and continues to attract, the attention of many investigators.

Oxidoreductases comprise a large class of enzymes that catalyze biological oxidation/reduction reactions. Because so many chemical transformation processes involve oxidation/reduction processes, the idea of developing practical applications of oxidoreductase enzymes has been a very attractive, but quite elusive, goal for many years [83], Applications have been sought for the production of pharmaceuticals, synthesis and modification of polymers, and the development of biosensors for a variety of clinical and analytical applications [83], In recent years, the use of oxido-reductive enzymes to catalyze the removal of aromatic compounds from...

The CRP on The Stability and Stabilization of Polymers under Irradiation was organized from 1994 to 1997 (IAEA-TECDOC-1062). The participants began research into the production of polymers under preparation of blends, which should withstand irradiation through the course of their useful lifetimes. They concluded that much remains to be learned in terms of understanding degradation mechanisms and phenomena. The application of radiation for the preparation of polymers for biomedical applications was the subject of the CRP on Radiation Synthesis and Modification of Polymers for Biomedical Applications implemented from 1996 to 2000 (IAEA-TECDOC-1324).
