Abstract:
The present invention provides a method to calibrate a NIR analyzer to measure monomer concentrations at one or more locations in a reactor system. The regression coefficients for the NIR analyzer are transferable between reactors using the same process (solution polymerization to solution polymerization) and may be used to control the reaction, or calibrate flow meters on line.
