Poly(alkylene glycol) - PAG copolymers are the most commonly used polymer quenchants in the world today. One of the distinguishing and advantageous features of these polymers is their ability to undergo thermal separation. This may occur at the hot metal interface during quenching or in solution as a means of recycling contaminated quench baths. In this paper, the use of electron spin resonance (ESR) spectroscopy to characterize PAG polymers that have been thermally separated from aqueous solution will be reported. Exploratory studies using ESR spectroscopy to characterize thermally separated polymer films during quenching will also be reported.
