| Abstract: | Free radical bulk and emulsion co‐ and terpolymerizations of conjugated linoleic acid (CLA) with styrene (Sty) and butyl acrylate (BA) were performed at 80 °C. The polymerizations were monitored using an attenuated total reflectance Fourier transform infrared (ATR‐FTIR) spectroscopic probe. Bulk polymerizations were monitored off‐line while emulsion polymerizations were monitored in‐line. Absorbance peaks related to the monomers and polymer were tracked to provide conversion and polymer composition data using a multivariate calibration method. Off‐line measurements using gravimetry and 1H‐NMR spectroscopy were compared to the ATR‐FTIR data and no significant differences were detected between the measurement methods. © 2016 Wiley Periodicals, Inc.
