Title (EN) POLYTRIMETHYLENE TEREPHTHALATE COMPOSITION PARTICLES AND PROCESS FOR PRODUCING THE SAME
(FR) PARTICULES DE LA COMPOSITION POLYTRIMETHYLENE TEREPHTALATE ET LEUR PROCEDE DE PRODUCTION
Abstract: front page image
(EN)Polytrimethylene terephthalate composition particles in which trimethylene terephthalate units account for at least 80 wt.% of the repeating units and the intrinsic viscosity is 0.8 to 2 dl/g, characterized in that (a) the particle size is 3 mm or smaller and the weight per particle is smaller than 1 mg; (b) the terminal carboxy content is 25 meq/kg or lower; and (c) the cyclic dimer content is 1.5 wt.% or lower.
(FR)L'invention concerne des particules de la composition polytriméthylène téréphtalate, dans lesquelles des unités de triméthylène téréphtalate représentent au moins 80 % en poids des unités récurrentes, la viscosité intrinsèque étant de 0,8 à 2dl/g, qui se caractérisent en ce que (a) leur taille est au maximum de 3 mm et le poids par particule est inférieur à 1 mg; (b) la teneur en carboxy terminal est au maximum de 25 meq/kg; et (c) la teneur en dimère cyclique est au maximum de 1,5 % en poids.
