Paper Abstract

Photopolymers are widely used in the electronic and printing industries. These materials usually consist of a plastisized polymer matrix, photoinitiator, monomer and a variety of chain transfer agents. Polymerization in photopolymer films is an interesting process but difficult to monitor. To facilitate the development of the new photopolymers and optimization of an imaging regime a method for the real-time nondestructive monitoring of reaction kinetics and molecular transport in photopolymers during photopolymerization was developed and applied. A change in the intensity of the fluorescence emitted by photopolymer films containing the fluorescent monomer, N-vinylcarbazole, is used to monitor the photopolymerization process. The mechanism of inhomogeneous polymerization in photopolymers is discussed.
