Title
(EN) POLYESTER POLYOL FOR USE IN POLYURETHANE
(FR) POLYESTER-POLYOL DESTINÉ À ÊTRE UTILISÉ DANS DU POLYURÉTHANE
Abstract
(EN)
The present invention relates to a polyester polyol, suitable for use in the manufacture of a polyurethane, suitable for use in the manufacture of a polyurethane, said polyester polyol having an ABA-structure, in which A represents a lactide-oligomer and in which B represents an initiator. The inventive feature is that the initiator comprises a reaction product comprising long chain dicarboxylic acid components having 18 or more carbon atoms, preferably dimer acids. Such components show a hydrophobic character. The invention also relates to a method for the manufacture of such polyester polyol. The invention further pertains to polyurethanes comprising the before-mentioned polyester polyol as well as the use of these polyurethanes as an elastomer having a high toughness. Said toughness is believed to originate from the combination of the hydrophobic character of the initiator and the hydrophilic character of the lactide parts in the polyol structure. The strength of the invented polylactide-polyurethane elastomers can be further improved by incorporating a carbodiimide in the elastomer material.

La présente invention concerne un polyester-polyol, approprié pour être utilisé dans la préparation d'un polyuréthane, ledit polyester-polyol présentant une structure ABA, dans laquelle A représente un oligomère de lactide et dans laquelle B représente un initiateur. La caractéristique de l'invention est que l'initiateur comprend un produit de réaction comprenant des composants d'acide dicarboxylique à longue chaîne comprenant 18 atomes de carbone ou plus, de préférence des acides dimères. De tels composants montrent un caractère hydrophobe. L'invention concerne également un procédé de préparation d'un tel polyester-polyol. L'invention concerne en outre des polyuréthanes comprenant le polyester-polyol susmentionné ainsi que l'utilisation de ces polyuréthanes comme élastomère présentant une haute solidité. On pense que ladite solidité provient de la combinaison du caractère hydrophobe de l'initiateur et du caractère hydrophile des parties de lactide dans la structure polyol. La résistance des élastomères de polylactide-polyuréthane selon l'invention peut être améliorée davantage par l'incorporation d'un carbodiimide dans le matériau élastomère.
