Abstract: Simple formalisms for thermal conductivity , thermal diffusivity D and specific heat Cp of both linear and cross-linked amorphous polymers has been presented. These relations explain successfully the dependence of these properties on temperature and amount of plasticizer. Present study reveals that the santicizer-160 forms cross-linkage among the linear chains of polyvinyl chloride (PVC). The structural transition at Tg, the anti-plasticization effect below Tg and plasticization effect above Tg, are clearly reflected in the trends of these properties. The calculated values of all the three properties for PVC plasticized with different amount of plasticizer (Santicizer-160: 10 phr, 20 phr and 30 phr) are in excellent agreement with the experimental values over a wide range of temperature, which includes glassy, leathery and rubbery regions. The maximum deviation in experimental and calculated values is less than 5% for all these properties.
