Abstract

Un método de preparación de un prepolímero de poli-isocianato, caracterizado porque consiste en: A. digerir un poli (tereftalato de alquileno) con un peso molecular superior a 15.000 en un disolvente reactivo seleccionado entre el grupo formado por dioles y trioles orgánicos, con un peso molecular de 62 a 500, hasta que el producto de digestión es soluble en acetona a la temperatura ambiente: B. hacer reaccionar el producto de digestión citado con un poli-isocianato orgánico para producir un prepolímero terminado en poli-isocianato sustancialmente exento de radicales hidroxilo sin reaccionar, y opcionalmente C. hacer reaccionar un prepolímero de poliisocianato con un poliol orgánico en presencia de un catalizador para la reacción de los radicales hidroxilo e isocianato.
