在80 °C下进行共轭亚油酸（CLA）与苯乙烯（Sty）和丙烯酸丁酯（BA）的自由基本体和乳液共聚和三元共聚。使用衰减全反射傅里叶变换红外（ATR-FTIR）光谱探针监测聚合。离线监测本体聚合，而在线监测乳液聚合。使用多变量校准方法追踪与单体和聚合物相关的吸光度峰以提供转化率和聚合物组成数据。将使用重量分析法和1H-NMR光谱法进行的离线测量与ATR-FTIR数据进行比较，未检测到测量方法之间的显著差异。© 2016 Wiley Periodicals，Inc. J.应用聚合物Sci.2016，133，43574.
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 and1H‐NMR spectroscopy were compared to the ATR‐FTIR data and no significant differences were detected between the measurement methods. © 2016 Wiley Periodicals, Inc.
