Photoacoustic spectroscopy was used to obtain the spectra of polyurethane rigid foam samples in powder and solid forms. This technique appears to be extremely efficient for studying optically opaque samples and can offer useful applications in such p

Poly(vinyl chloride) film shows substantial changes in its photoacoustic absorption spectra (PAS) on either irradiation or heating in the presence of O2 or N2. These spectral changes are due to the conjugation structures and carbonyl (group formation

A simple model based on a single process of a three body reaction has been used in this work for trimer formation. This model has successfully explained the dependence of monomer and trimer on temperatures. The binding energy, association energy, and

Polyurethane rigid foam shows substantial changes in its photoacoustic absorption spectra (PAS) on heating in the presence of air. These spectral changes are due to conjugated structures and quinone–imide formation, formed during degradation. The m
