Abstract
The degradation of polyethylene (LDPE) by H-ZSM-5 is investigated by vibrational spectroscopy, using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and inelastic neutron scattering (INS). DRIFTS results indicate initial interaction between LDPE and external silanol groups, and hydrogen bonding with some Brønsted acid sites. At low temperatures both techniques suggest minimal interactions between the LDPE and the internal acid site of the zeolite, suggesting initial interactions are primarily with the zeolite surface. At higher reaction temperatures, oligomerisation is observed on Brønsted acid sites.
