<p>The present invention relates to a process for characterizing a copolymer of ethylene and vinyl acetate (EVA) using a differential calorimetry analysis technique. This process consists in determining one or more values of characteristic(s) of said sample of EVA copolymer, one of which is a level of crosslinking of said sample. The process according to the invention 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.</p> |
