Title (EN) METHOD FOR MANUFACTURING STABLE POLYLACTIDE
(FR) PROCÉDÉ DE FABRICATION D'UN POLYLACTIDE STABLE
Abstract: front page image
(EN)The present invention pertains to a process for manufacturing polylactide comprising the steps of combining lactide with a polymerisation catalyst, subjecting the mixture to polymerization conditions to form polyiactide in the liquid state, adding an organic peroxide, subjecting the liquid polyiactide to a devola tiiisation step, and allowing the polylactide to solidify.
(FR)Cette invention concerne un procédé de fabrication d'un polylactide comprenant les étapes consistant à combiner le lactide avec un catalyseur de polymérisation, à soumettre le mélange à des conditions de polymérisation pour former le polylactide à l'état liquide, à ajouter un peroxyde organique, à soumettre le polylactide liquide à une étape de dévolatilisation, et à laisser le polylactide se solidifier.
