Abstract
Una composición de poliéster que comprende las siguientesunidades recurrentes:en donde:- en cualquier unidad, x es un entero seleccionado entre 2 a 6 inclusive;- en al menos una porción de las unidades, R es 1,3-difenilo;- en al menos una porción de las unidades, R es 1,4-difenilo; y- en la menos una porción de las unidades, R es 2,6-dinaftilo; y- en donde la densidad del poliéster es de por lo menos 1,365 g/cm3 aproximadamente.El poliéster según la reivindicación 1, caracterizado porque x es 2.El poliéster según la reivindicación 1, caracterizado porque la relación de unidades en donde R es 1,4-difenilo al total de las unidades en donde R es 1,3-difenilo y de las unidades en donde R es 2,6-dinaftilo, es de 80:20 a 96:4.A polyester composition comprising the following recurring units: wherein: - in any unit, x is an integer selected from 2 to 6 inclusive; - in at least a portion of the units, R is 1,3-diphenyl; - in al minus a portion of the units, R is 1,4-diphenyl; and - in at least a portion of the units, R is 2,6-dynaphthyl; and where the density of the polyester is at least approximately 1,365 g / cm3. The polyester according to claim 1, characterized in that x is 2. The polyester according to claim 1, characterized in that the ratio of units where R is 1 , 4-diphenyl to the total of the units where R is 1,3-diphenyl and of the units where R is 2,6-dinaphthyl, is from 80:20 to 96: 4.
