Abstract

La presente invención se refiere a composición mejorada de polímero spandex, segmentado y lineal de poliuretano-urea, que se produce por reacción de un polímero de terminación hidroxílica con un diisocianato orgánico para formar un polímero con terminación de isocianato, cuya cadena se extiende con una diamina para proveer al polímero spandex con una resistencia incrementada en control del cloro, contra las manchas de humedad y contra el enmohecimiento; en donde la mejora comprende, en combinación: a) que el polímero de terminación hidroxílica es un policarbonato que se selecciona del grupo consiste en poli(pentano-1,5-carbonato)diol, poli(hexano-1,6-carbonato)diol y los copolímeros o las mezclas de los mismos; b) que el diisocianato orgánico se selecciona del grupo consistente en poli(pentano-1,5-carbonato)diol, poli(hexano-1,6-carbonato)diol y los copolímeros o las mezclas de los mismos; b)que el diisocianato orgánico se selecciona del grupo consistente en diisocianato de p,p'-metilendifenilo, 4,4'me-tilen-bis(ciclohexilisocianato), diisocianato de alfa, alfa, alfa'-tetrametil-p-xilileno, diisocianato de alfa, alfa, alfa', alfa'-tetrametil-m-xilileno y mezclas de los mismo; c) que la diamina extendedora de la cadena se selecciona del grupo consistente en hidracina y en diaminas de la fórmula H2N-R-NH2, en cuya fórmula R tiene de 2 a 8 átomos de carbono y es un grupo de alquileno, un grupo alicíclico, un grupo de xilileno tetracloro-sustituido y mezclas de dichos compuestos.
