Title (EN) POLYESTER COMPOSITIONS WHICH COMPRISE TETRAMETHYL CYCLOBUTANEDIOL AND ETHYLENE GLYCOL, WITH IMPROVED CATALYST SYSTEM
(FR) COMPOSITIONS À BASE DE POLYESTER COMPRENANT DU TÉTRAMÉTHYL-CYCLOBUTANEDIOL ET DE L'ÉTHYLÈNE GLYCOL, AVEC SYSTÈME CATALYSEUR AMÉLIORÉ
Abstract: front page image
(EN)Described as one aspect of the invention are polyester compositions including at least one polyester which comprises: (a) a dicarboxylic acid component comprising about 90 to about 100 mole % of terephthalic acid residues; and (b) a glycol component comprising: (i) about 10 to about 27 mole % 2,2,4,4-tetramethyl-1,3- cyclobutanediol residues; and (ii) about 73 to about 90 mole % ethylene glycol residues; wherein the total mole % of the dicarboxylic acid component is 100 mole %, and wherein the total mole % of the glycol component is 100 mole %; wherein the inherent viscosity of the polyester is from 0.50 to 0.8 dL/g; and wherein the L* color values for the polyester is 90 or greater. The polyesters may be manufactured into articles.
(FR)Selon un certain aspect, l'invention concerne des compositions à base de polyester comprenant au moins un polyester qui comprend : (a) un constituant acide dicarboxylique comprenant environ 90 à environ 100 % en mole de résidus acide téréphtalique ; et (b) un constituant glycol comprenant : (i) environ 10 à environ 27 % en mole de résidus 2,2,4,4-tétraméthyl-1,3-cyclobutanediol ; et (ii) environ 73 à environ 90 % en mole de résidus éthylène glycol ; le pourcentage molaire total du constituant acide dicarboxylique étant de 100 %, et le pourcentage molaire total du constituant glycol étant de 100 % ; la viscosité inhérente du polyester allant de 0,50 à 0,8 dL/g ; et la valeur L* de la couleur pour le polyester étant supérieure ou égale à 90. Ces polyesters permettent la fabrication d’articles.
