This book introduces the theory of light-induced polymerization utilizing ultraviolet (UV) and visiblelight and electron beams (EB) as the initiators, beginning with an analysis of the physical chemistryof photopolymerization and its advantages and disadvantages compared to other types. The volumeexplains how the underlying chemical reactions relate to the types of processes selected and productquality, with an in-depth consideration of the raw materials and equipment required for efficient UV andEB curing. Special attention is given to the principles of formulation and to applications where this typeof curing leads to higher quality products at lower costs.
