Thus isolation of oxoammonium salts on insoluble, cross-linked polymer supports was investigated together with integration of the active resins in polymer-assisted solution phase synthesis [11], These isolated oxoammonium salts could be employed in a water-free system with the intention of generating a highly reactive oxidizing agent that avoids over-oxidation to the acid, because of the absence of water. 

Polymer-supported carbanion equivalents are the obvious supplement to polymer-supported access to reactive electrophiles either by oxidizing polymers or by release of carbenium ions. The combination of an oxidizing resin with a support carrying carbanion equivalents will be especially rewarding, enabling reaction sequences with C-C coupling steps and thus opening access to a wealth of potentially relevant products.

Expertise in resin and polymer synthesis has made available materials which can function as solid, but insoluble, oxidizing or reducing agents they are sometimes called redox resins or electron exchangers . Their reactivity in the latter sense is due to the polymer matrix carrying functional groups which may be reversibly oxidized and reduced. Studies of these polymers have involved two main kinds of... 

The poly(phenylene oxide) polymer was commercial resin obtained from Noryl Products Division, General Electric Company, Selkirk, NY. Solvents were spectroscopic grade. All other reagents were obtained from commercial sources and were used as received. 

Significant effort was put into the oxidation of benzoic acid to cis,cis-muconic acid via a multi-step reaction catalyzed by whole microbial cells 21 24]. Cis,ris-muconic acid is used as raw material for the synthesis of resins and polymers (precursor of adipic acid). Furthermore, it is widely used as building block in the synthesis of pharmaceuticals and agrochemicals.

Vinyl compounds are widely used in the industry in manufacture of various resins and polymers and the like. Methacrylic acid and methyl methacrylate are especially attractive as row materials of polymethyl methacrylate that is an important polymer so-called "organic glass." Until a new process consisting of two-step oxidation of isobutylene was commercially practiced in 1982, methyl methacrylate had been produced by the "Acetone Cyanohydrine Process," which uses acetone, hydrogen cyanide, methanol, and sulfuric acid as raw materials. Technical and economical drawbacks of this process have spurred a considerable industrial research effort to develop an alternate route to methacrylic acid and methyl methacrylate. Therefore, many attempts have been focused on the production of these compounds by aldol-type condensation using HCHO. 

Ultraviolet and fluorescent microscopy has been applied to a variety of polymer systems to investigate changes of morphology and composition on the scale of 0.25 ym upwards. Studies are briefly described on the behaviour of stabilisers in polypropylene, diffusion of additives in polymers, spherulite morphology, polyolefin oxidation, inhomogeneities in epoxy resins and polymer blends.
