Thermophysical properties of polypentadecanolactone
In this paper we present thermodynamic properties and crystallization kinetics of the aliphatic polyester, polypentadecanolactone, with largely unknown properties. Experimental specific heat capacity values, melting and glass transition characteristics are analysed, as are the crystallization processes during different conditions. Equilibrium melting temperatures are deduced with the Hoffman-Week extrapolation method. The overall crystallization kinetics are analysed with the Avrami equation, and the Lauritzen-Hoffman crystallization theory is applied to the data.
