“…The technique can be operated in an attenuated total reflection (ATR) as well as in a transmission mode. 1,,–9 Sinusoidal deformation combined with a modulation/demodulation technique provides an excellent signal-to-noise ratio (S/N) by averaging the response over a large number of cycles of measurement. In addition, with ATR mode detection, even molecular groups, such as C=O, COO, and imide groups, with very strong IR absorption characteristics, which often suffer from spectral saturation in a conventional transmission mode DIRLD experiment, can be studied.…”

An improved time-resolved soft-pulse dynamic compression attenuated total reflection (ATR) step-scan Fourier transform rheo-optical system has been developed. This system was used to observe reversible dynamic responses of poly(ethyleneterephthalate) (PET) and poly(p-phenylene biphenyltetracarboximide) (BPDA-PDA) films. In the case of PET, reversible nonlinear dynamic responses were observed in the C=O stretching vibration. The nonlinear responses decreased with decreasing compressive strain from 0.045 to 0.018. For the C-O stretching bands associated with the backbone structure of the PET, the nonlinear responses were very small. Characteristic burst-like reversible nonlinear dynamic responses can be seen in the in-phase and out-of-phase C=O stretching vibrations of cyclic imides, and phenyl ring deformation bands in the PDA parts of the BPDA-PDA. The results suggest the presence of inter-molecular interaction between C=O of cyclic imides and the phenyl ring groups of the PDA parts. The present method shows promise for characterizing a wide variety of polymeric materials, including polymer alloys, blends, composites, and copolymers and semicrystalline polymers.

“…Deformation of poly(p-phenylene biphenyltetracarboximide) was analyzed with the combined aid of density functional theory calculation. 2D correlation spectroscopy based on such dynamic ATR-IR compression modulation was applied to the study of iso-phthalate based polyester with triphynylphosphate [290]. It was shown that the orientation dynamics was different with different triphynylphosphate level.…”

Two‐dimensional correlation spectroscopy (2DCOS) is a mathematical method whose basic principles were first proposed by Noda in 1986. Up to the present, 2DCOS has been widely used to study spectral variations of different chemical species under various external perturbations (eg, temperature, pressure, concentration, time, electromagnetic). By spreading peaks along a second dimension, 2DCOS can sort out complex or overlapped spectral features and get an enhanced spectral resolution. Owing to the different response of different species to external variable, additional useful information about molecular motions or conformational changes can be extracted, which cannot be obtained directly from conventional one‐dimensional spectra. Perturbation‐correlation moving window (PCMW) is a newly developed technique based on 2DCOS. Except for its original ability in determining transition points, PCMW can additionally monitor complicated spectral variations along the perturbation direction. In this critical review, we focus on the application of 2DCOS and PCMW to the characterization of polymers, which are classified in six specific topics: synthetic functional polymers, bio‐ and natural polymers, glass transition, crystallization and melting of polymers, water diffusion in polymer films, polymer blends and nanocomposites, and polymer‐related reactions.
