Thermodynamics of addition polymerisation. Part 3. The heat capacity, entropy, enthalpy and free energy of a random ethylene/propylene copolymer

Abstract: An adiabatic, vacuum calorimeter has been used to measure the heat capacity of a random ethylene/propylene copolymer, containing 31 mole per cent propylene, from 80 to 320°K. An estimate has been made of heat capacity values below 80°K. Entropy, enthalpy and free energy values have been derived and are listed a t ten degree intervals. The difference (1.2 cal deg-1 mole repeat unit-l) between the observed entropy (15.1 & 0.2 cal deg-1 mole repeat unit-1) and that calculated from previously published data for po… Show more
