✦ Synopsis

The hot-wire standard technique, mostly used for ceramic materials, was adapted to determine the thermal conductivity of nylon 6,6, polypropylene, poly(viny1 chloride), and poly(methy1 methacrylate). The results obtained showed that the hot-wire standard technique can be used with accuracy and reproducibility to measure the thermal conductivity of polymers. In the second stage, to verify the effect of the use of a lignin (a "macromonomer") in the thermal conductivity of phenolic resins, this technique was applied to phenolformaldehyde and phenol-lignin-formaldehyde resins.
