A ONE STEP PROCESS FOR THE PELLETISATION OF POLY LACTIC ACID WITHOUT MELT PROCESSING

The present invention relates to a one step process for the palletization of poly lactic acid of molecular weight in the range of 6-8 lakhs without melt processing such that the pellets obtained exhibit minimal molecular weight reduction. The molecular weight of poly lactic acid (PLA) in the obtaine...

Beschreibung
Zusammenfassung:	The present invention relates to a one step process for the palletization of poly lactic acid of molecular weight in the range of 6-8 lakhs without melt processing such that the pellets obtained exhibit minimal molecular weight reduction. The molecular weight of poly lactic acid (PLA) in the obtained pellets is retained in the range of 6-8 lakhs. La présente invention concerne un procédé en une étape destiné à la palettisation de l'acide polylactique de masse moléculaire dans la plage de 6-8 lakhs sans traitement par fusion de telle sorte que les granulés obtenus présentent une réduction minimale de poids moléculaire. Le poids moléculaire de l'acide polylactique (PLA) dans les granulés obtenus est retenu dans la plage de 6 à 8 lakhs.
