Abstract:
The present invention is directed to a method for the manufacture of stable lactide particles, more specifically lactide particles which are stable enough to be stored and transported at room temperature and have a quality high enough for use as starting material for polylactic acid. The lactide particles are obtained via a flaking process, comprising the contacting of a continuous flow of molten lactide with a surface on which the lactide solidifies and subsequently is removed from said surface.
