Abstract
A process for characterizing a copolymer of ethylene and vinyl acetate (EVA) using a differential calorimetry analysis technique. This process is determining one or more values of characteristic(s) of a sample of EVA copolymer, one of which is a level of crosslinking of the sample. The process makes it possible to determine not only the degree of crosslinking, but also the vinyl acetate content and the molecular mass of an EVA sample, in a simple, rapid, easy and precise manner.
