THERMAL-CONDUCTIVITY OF POLYMERS BY HOT-WIRE METHOD

The hot-wire standard technique, mostly used for ceramic materials, wa s adapted to determine the thermal conductivity of nylon 6,6, polyprop ylene, poly(vinyl chloride), and poly(methyl methacrylate). The result s obtained showed that the hot-wire standard technique can be used wit h accuracy and reproducibility to measure the thermal conductivity of polymers. In the second stage, to verify the effect of the use of a li gnin (a ''macromonomer'') in the thermal conductivity of phenolic resi ns, this technique was applied to phenol-formaldehyde and phenol-ligni n-formaldehyde resins.
