Title (EN) POLYOLS WITH REDUCED CYCLIC OLIGOMER CONTENT AND THERMOPLASTIC POLYURETHANE COMPOSITIONS THEREOF
(FR) POLYOLS À TENEUR RÉDUITE EN OLIGOMÈRE CYCLIQUE ET LEURS COMPOSITIONS DE POLYURÉTHANE THERMOPLASTIQUE
Abstract:
(EN) The present invention relates to a hydroxyl-terminated polyester intermediate which comprises the reaction product of one or more C2 to C12 linear diols with one or more C2 to C12 linear diacids and which has reduced cyclic oligomer content. The hydroxyl-terminated polyester intermediate may be made in the presence of an enzyme or treated with an enzyme to reduce the cyclic oligomer content. The present invention also relates to thermoplastic polyurethane compositions made with the hydroxyl-terminated polyester intermediate having reduced cyclic oligomer content.
(FR) La présente invention concerne un intermédiaire de polyester terminé par un groupe hydroxyle qui comporte le produit réactionnel d'un ou de plusieurs diols linéaires en C2 à C12 avec un ou plusieurs diacides linéaires en C2 à C12 et qui présente une teneur réduite en oligomère cyclique. L'intermédiaire de polyester terminé par un groupe hydroxyle peut être fabriqué en présence d'une enzyme ou traité avec une enzyme pour réduire la teneur en oligomère cyclique. La présente invention concerne également des compositions de polyuréthane thermoplastique fabriquées avec l'intermédiaire de polyester terminé par un groupe hydroxyle présentant une teneur réduite en oligomère cyclique.
