  • Patent number: 11084900
    Abstract: A polyester single layer film according to an embodiment of the present invention has low haze and low oligomer characteristics, has a more bluish color coordinate, and has a low inorganic metal content. Accordingly, the polyester single layer film may be used as a base film of a heat-resistant protective film and a light-scattering preventive film, as well as an ITO and non-ITO base film (for Ag nanowire, or the like) used in recent touch panels. In addition, since the transmittance at a wavelength of 550 nm is relatively high due to less impurity, the polyester single layer film may be used as a base film of a prism for a backlight unit (BLU) and a diffusion sheet.

    Abstract: 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, the polyester polyol having an ABA-structure, in which A represents a lactide-oligomer and in which B represents an initiator. The initiator includes a reaction product having long chain dicarboxylic acid components having 18 or more carbon atoms. The invention also relates to a method for the manufacture of the polyester polyol. The invention further pertains to polyurethanes including the before-mentioned polyester polyol as well as the use of these polyurethanes as an elastomer having a high toughness. The 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.

  • Patent number: 9850339
    Abstract: A liquid crystalline polyurethane elastomer is produced by reacting an isocyanate component, a high-molecular-weight polyol component and a mesogenic diol represented by formula (1), and having a crosslinking site that is introduced by a tri-functional or higher isocyanate in the isocyanate component and/or a high-molecular-weight polyol having a number average molecular weight of 400 or more and less than 7000 and having three or more hydroxy groups, in the high-molecular-weight polyol component, wherein the melting point of a mesogenic unit does not exist in a temperature range lying between the glass transition temperature (Tg) and the (liquid crystal phase)-to-(isotropic phase) transition temperature (Ti) of the polyurethane elastomer, and a liquid crystal is developed at a temperature between the Tg and the Ti. (In the formula, X represents an alkylene group having 3 to 20 carbon atoms; and Y represents a single bond, —N?N—, —CO—, —CO—O— or —CH?N—).
