Abstract:

The thermal conductivity of polymers at high temperature were determined by flash method. It indicated that rate of conduction of heat away from the surface in contact and was estimated at maximum temperature. The pre-polymers of polyquinazolinedione, and polyquinazolones were prepared and coated on stainless steel substrate. The transient tune for all of the polymers were measured from their curve history and from the results of the computer, thermal conductivities were determined. These were compared with polyphenylene sulphide. It was concluded that the thermal conductivities can be related to interatomic binding forces. The materials resemble that of the solid state material like graphite.
