Study of the Conformations of Poly(Epsilon-Caprolactam) and Poly(Epsilon-Caprolactam)-Polybutadiene Block-Copolymers by FTIR Spectroscopy with Photoacoustic Detection and by Micro-Raman Confocal Spectroscopy
The conformations of poly(epsilon-caprolactam) and of poly(epsilon-caprolactam)-block-polybutadiene copolymers were investigated by Fourier Transform infrared spectroscopy with photoacoustic detection (PA-FTi.r.) and by micro-Raman confocal spectroscopy. The lowering of the planar conformation content with increasing concentration of butadiene units was confirmed. In the surface layers formed by rapid saw-cutting and in the islands probably formed by microtome cutting, the content of the planar conformation was reduced. The content of the planar conformation increases on water treatment.
