Abstract
AbstractThe stiffness of the polymer chains provokes a part of the acoustical low frequency phonons in polymer crystals to behave like free particles charged with mass, as far as their energy-momentum-relation is concerned. The influence of this "mass" on the 3-phonon-processes and on the phonon-electron-interaction in the isolated linear chain, in a Bravais lattice built up of linear chains, and in the isolated planar zig-zag-chain is investigated. It is shown that the "inert" phonons are especially exposed in the case of phonon-phonon-and phonon-electron-interaction.
