Abstract
A general outline of new applications of lasers in polymer photochemistry is given. The fields covered include the kinetic and mechanistic study of various elementary processes (in solution model compounds) by laser spectroscopies and the extension of this approach to practical systems (solids or in polymerization samples, thin films) by holographic techniques or real‐time infrared spectroscopy. Stress is laid on the great importance of laser techniques in understanding the fundamental aspects of the processes involved in polymer photochemistry.
Highlights
The applications of lasers in polymer photochemistry spring from the meeting point of two fascinating research fields
Time-resolved laser spectroscopy gives a better insight into the dynamics of the excited states and provides a valuable description of the processes involved, which may be helpful to explain the relative efficiency of photoinitiators and to inquire into possible improvements of the reactivity of various molecular structures
Other possible uses of intense laser irradiation include three-dimension modelling, the curing of thick sections of polymers[54] or of composites and the high speed treatment of optical fibers or microcircuits[69] by UV curable coatings. This survey is aimed at taking stock of the recent developments of laser techniques for the study of photo-induced polymerizations and all kinds of photoprocesses taking place in polymer matrixes
