Abstract:
A method for screening polymerization reactants, catalysts or reaction conditions, comprising:irradiating at least one reaction sample (2) comprising fluorescence emitting Fries products with light of a defined excitation wavelength (4); monitoring a fluorescence spectrum (10) emitted from the Fries products of the sample (2) by computing principal components of spectra emitted from the irradiated sample; comparing the monitored fluorescence spectrum (10) to a database that comprises a Fries product fluorescence spectrum correlated with a reaction parameter of interest to determine a correlation between the monitored fluorescence spectrum (10) and the database Fries product fluorescence spectrum; determining a reaction parameter of interest of the irradiated reaction sample from the correlation; and correlating the reaction parameter of interest with a performance of the polymerization reactants, catalysts or reaction condition.
