Manufacture of polylactide-based articles by rotational molding

A process for the manufacture of a polylactide-based article by rotational molding, comprising:

• a) placing polylactide in a mold,
• b) subjecting the polylactide to a rotational molding comprising heating to a temperature of between 150° C. and 230° C. to obtain the article,
• c) cooling the mold or the article obtained, and
• d) removing the article from the mold,
• wherein the optical purity of the polylactide is greater than 92% by weight;
• wherein the polylactide is in the form of particles having a size of between 20 μm and 2000 μm;
• wherein the cooling of the mold or of the article obtained in stage (c) comprises the following stages:
• i) cooling down to a temperature of between 100° C. and 150° C.,
• ii) maintaining at this temperature for 1 to 60 minutes,
• iii) cooling down to a temperature of between ambient temperature and a temperature of less than 100° C.
