Abstract
The conformations of poly(epsilon-caprolactam) and of poly(epsilon-cap rolactam)-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 plana r conformation content with increasing concentration of butadiene unit s was confirmed. In the surface layers formed by rapid saw-cutting and in the islands probably formed by microtome cutting, the content of t he planar conformation was reduced. The content of the planar conforma tion increases on water treatment. (C) 1997 Elsevier Science Ltd.
