Photoinitiating systems for polymerization reactions are largely encountered in a variety of traditional and high-tech sectors, such as radiation curing, (laser) imaging, (micro)electronics, optics, and medicine.
This book extensively covers radical and nonradical photoinitiating systems and is divided into four parts:
* Basic principles in photopolymerization reactions
* Radical photoinitiating systems
* Nonradical photoinitiating systems
* Reactivity of the photoinitiating system
The four parts present the basic concepts of photopolymerization reactions, review all of the available photoinitiating systems and deliver a
thorough description of the encountered mechanisms. A large amount of experimental and theoretical data has been collected herein. This
book allows the reader to gain a clear understanding by providing a general discussion of the photochemistry and chemistry involved.
The most recent and exciting developments, as well as the promising prospects for new applications, are outlined.
