A group contribution model for the prediction of the thermal conductivity of polymer melts

A group contribution model was proposed for the prediction of the thermal c onductivity of polymer melts. The model requires only the existing group co ntribution methods for the estimation of specific heats, densities, and mel ting temperatures in the calculation of thermal conductivity for polymer me lts. For 11 polymer melt systems tested, predictive accuracy of the model i s normally better than 10%. Because only group parameters are needed in the calculation, this model is predictive and is very convenient for practical use.
