“…Most of these precursors are known as inhibitors of radical polymerization. [70][71][72][73][74][75][76][77][78] This review focuses on the major progress made in (i) the one-pot radical preparation of alkoxyamines from nitroxide precursors and (ii) the development of in-situ NMP processes and their understanding and optimization. The major advantage of in-situ versus traditional NMP is a less costly implementation, which is highly desirable when producing commodity polymers.…”

SynopsisThe major photoproduct from irradiation of triphenylsulfonium salts is a Bronsted acid. This photochemical process has been used in several polymer film applications where the acid is used for crosslinking of films or other acid catalyzed reactions. Despite the widespread application of these materials, very little is known about the efficiency of acid generation in polymer films or the extent of the catalytic chain. This paper describes the use of a merocyanine dye technique to analyze for acid production in polymer films. The amount of acid produced on irradiation can be determined by this method and the extent of the catalytic chain can then be determined.

The irradiation of triarylsulfonium salts produces Brönsted acid along with diarylsulfide products. This photochemical conversion has been applied in several areas of polymer film technology including imaging and curing of films. This paper discusses the dependency of acid generation in polymer films on the structures of both polymer and sulfonium salt. The results suggest that the structures of both polymer and sulfonium salt. The results suggest that the efficiency of acid generation is dependent on the interaction between polymer structure and the charged sulfonium salt. Studies have been carried out for both deep‐UV and electron beam irradiation of polymer films. The variation of acid generation with sulfonium salt loading has been determined. Finally the effect of accelerating voltage on the amount of acid generation following electron beam irradiation is discussed. ESR spectroscopy has been done on films after uv irradiation to determine the nature of the radicals which are formed.
