| description | The present invention relates to a thermoplastic polyurethane obtained from a reaction mixture comprising: (a) at least one cyclic polyisocyanate, and (b) at least one polyol, in which the thermoplastic polyurethane has gas barrier properties which are better than the gas barrier properties of polyethylene terephthalate (PET) measured under the same circumstances, characterised in that the thermoplastic polyurethane is an essentially amorphous material based on the absence of a melting peak in a DSC curve, and the thermoplastic polyurethane has a glass transition temperature Tg situated between 60°C and 99,5°C in a DSC curve, and both curves were obtained with differential scanning calorimetry (DSC) as mentioned in the description. The invention also relates to uses of this material, hollow and hard bottles obtained from this material and methods for obtaining the material and bottles.
La présente invention se rapporte à un polyuréthane thermoplastique obtenu à partir d'un mélange réactionnel comprenant : (a) au moins un polyisocyanate cyclique, et (b) au moins un polyol, dans lequel le polyuréthane thermoplastique a des propriétés de barrière aux gaz qui sont meilleures que les propriétés de barrière aux gaz du polyéthylène téréphtalate (PET) mesurées dans les mêmes conditions, caractérisé en ce que le polyuréthane thermoplastique est un matériau sensiblement amorphe sur la base de l'absence de pic de fusion dans une courbe de DSC, et le polyuréthane thermoplastique a une température de transition vitreuse Tg située entre 60 °C et 99,5 °C dans une courbe de DSC, et les deux courbes ayant été obtenues par calorimétrie différentielle à balayage (DSC) comme mentionné dans la description. L'invention se rapporte également à des utilisations de ce matériau, à des bouteilles creuses et dures obtenues à partir de ce matériau et à des procédés d'obtention du matériau et des bouteilles. |
