(36) What has been described above includes examples of the present specification.

EXAMPLES

(37) The bulk thermal conductivity (T/C) is determined, unless mentioned otherwise in the examples, by transient method using Hot Disk TPS 500 S instrument. Number-average molecular weight (M.sub.n) and poly dispersity index (PDI), with reference to monodisperse polystyrene standards, were determined using Agilent 1260 Infinity gel permeation chromatography system equipped with solvent degasser, Agilent Mixed-BLS (10 um) column, ELSD and RID detector. Melting points were determined by Differential Scanning Calorimetry (DSC) on a TA Instrument (Q 1000) at a heating rate of 10° C. min.sup.−1 under a nitrogen atmosphere.
