Abstract:
The present invention relates to a method for quantification of the amount of lactide in a lactide-based polymeric matrix by means of Infra Red Spectroscopy measurement. According to the invention the quantification is based on measurements performed on absorptions in the near Infra Red region of the electromagnetic spectrum. The invented method allows a rapid, easy and cheap quantification of lactide in a polymeric matrix, especially in PLA.
