Measurement of the Heat of Fusion of Crystalline Polymers by a Calorimetric Melting Point Depression Technique

  • J. R. Knox


The accurate measurement of percent crystallinity in polymers by calorimetric techniques depends upon having a reliable value for the heat of fusion. Use of adiabatic calorimeters to obtain heats of fusion, however, requires knowledge of the percent crystallinity, at the temperature from which the enthalpic base line is drawn. This temperature is generally well above the temperature at which independent measurements of the degree of crystallinity are made, and heat of fusion values obtained via this technique are no more accurate than the percent crystallinity values used in the calculation.
