Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The kinetics of poly(ethylene terephthalate) melting are studied by DSC and treated in the framework of a nucleation kinetic model. The study focuses on the temperature dependence of the effective activation energy of melting. A theoretical dependence is derived from the model and an experimental one from the Kissinger plot. It is demonstrated that the theoretical dependence satisfactorily predicts the experimental one and fitting the former to the latter can be used for estimating the surface free energy of a nucleus. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3x90rbgh" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
