THERMOPHYSICAL PROPERTIES OF POLYPENTADECANOLACTONE

In this paper we present thermodynamic properties and crystallization kinetics of the aliphatic polyester, polypentadecanolactone, with larg ely unknown properties. Experimental specific heat capacity values, me lting and glass transition characteristics are analysed, as are the cr ystallization processes during different conditions. Equilibrium melti ng temperatures are deduced with the Hoffman-Week extrapolation method . The overall crystallization kinetics are analysed with the Avrami eq uation, and the Lauritzen-Hoffman crystallization theory is applied to the data. (C) 1998 Elsevier Science Ltd.
