CLAIMS

We claim:

1. A one step process for the synthesis of PLA pellets comprising dissolving poly lactic acid of molecular weight in the range of 6-8 lakhs in a solvent followed by extrusion at the temperature ranging from 25° C. to 30° C. to obtain fibre morphologies, said fibres are cut to...

DESCRIPTION

FIELD OF THE INVENTION

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...
