Title
(EN) PROCESS FOR THE PRODUCTION OF THERMOPLASTIC POLYESTER
(FR) PROCÉDÉ DE PRODUCTION D'UN POLYESTER THERMOPLASTIQUE
Abstract
(EN)
The present invention relates to a process for the production of a thermoplastic polyester using a reaction mixture comprising a dicarboxylic acid having a melting temperature of ≥ 200°C wherein the dicarboxylic acid is introduced to the process in the form of particles having an average particle diameter of ≥ 100 µm. Such process results in a reduction of the polymerisation time. Furthermore, it allows for the production of thermoplastic polyesters having a desired balance of intrinsic viscosity and carboxylic end group content at a reduced polymerisation time.
(FR)
La présente invention concerne un procédé de production d'un polyester thermoplastique à l'aide d'un mélange réactionnel comprenant un acide dicarboxylique ayant une température de fusion ≥ 200 °C, l'acide dicarboxylique étant introduit dans le procédé sous forme de particules ayant un diamètre moyen de particule ≥ 100 µm. Un tel procédé permet de réduire le temps de polymérisation. En outre, il permet la production de polyesters thermoplastiques présentant un équilibre souhaitable entre la viscosité intrinsèque et la teneur en groupes terminaux carboxyliques en un temps de polymérisation réduit.
