Analytical instruments for monitoring photopolymerizations

This invention is directed to a new, inexpensive analytical instrument that can be used to study and evaluate such essential parameters as light intensity, photoinitiator concentration, and monomer reactivity in a wide variety of UV photopolymerization curing applications. The device provides real-time information as the sample proceeds through the photoreactive phase. Through the direct, continuous, and remote monitoring of the sample using optical pyrometery, the temperature of the monomer undergoing photopolymerization can be obtained as a function of time.
