The lattice thermal conductivity (K) of amorphous polymer at low temperatures has been analyzed by expressing its total lattice thermal conductivity as a sum of the three contributions as K=KBE +KEM+KAP, Where KBE is the contribution due to those phonons is can interact with crystal boundaries, KEM is due to those phonons which have frequencies less than the plateau frequency (wpt) and KAP is d [...]
