Abstract

L'invention concerne un procédé comprenant les étapes consistant à a) faire réagir en fusion au moins un glycol et au moins un acide dicarboxylique afin d'obtenir un polyester ayant une valeur IhV d'au moins 0,5 dl/g environ, ledit glycol étant sélectionné dans le groupe comprenant des glycols ayant jusqu'à 10 atomes de carbone et des mélanges de ceux-ci, et l'acide dicarboxylique étant sélectionné dans le groupe comprenant des acides alkyle dicarboxyliques ayant de 2 à 16 atomes de carbone, des acides aryle dicarboxyliques ayant de 8 à 16 atomes de carbone et des mélanges de ceux-ci; et b) transformer ledit polyester en articles façonnés directement depuis l'étape a). Ainsi, la présente invention décrit un procédé de coulée directe dans le moule afin de former des articles en polyester.
