    Abstract: Provided are a multi-block copolymer, a pressure-sensitive adhesive composition, a method of preparing a multi-block copolymer, a pressure-sensitive adhesive polarizing plate, and a liquid crystal display device. The pressure-sensitive adhesive composition including the multi-block copolymer may have excellent durability regardless of a temperature and/or humidity. In addition, the method of preparing a multi-block copolymer may prepare a multi-block copolymer increased in molecular weight which is structurally controlled with a simple process using a compound containing at least two halogen atoms. Accordingly, when included in a pressure-sensitive adhesive resin, the multi-block copolymer may have excellent cohesive strength in the resin, and a network structure during curing, and thus, when applied to a pressure-sensitive adhesive composition, the multi-block copolymer may be usefully applied to an optical member due to excellent durability regardless of a temperature and humidity.

    Abstract translation: 提供多嵌段共聚物，压敏粘合剂组合物，制备多嵌段共聚物的方法，压敏粘合剂偏光板和液晶显示装置。 包含多嵌段共聚物的压敏粘合剂组合物可以具有优异的耐久性，而不管温度和/或湿度如何。 此外，制备多嵌段共聚物的方法可以制备分子量增加的多嵌段共聚物，其结构上用简单的方法使用含有至少两个卤素原子的化合物进行控制。 因此，当包含在粘合剂树脂中时，多嵌段共聚物可以在树脂中具有优异的内聚强度，并且在固化期间可以具有网状结构，因此当应用于压敏粘合剂组合物时，多嵌段 无论温度和湿度如何，由于优异的耐久性，共聚物可以有效地应用于光学部件。

    Abstract: Provided is a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition may form a pressure-sensitive adhesive having a fine phase separation structure by a block copolymer including a hard segment and a soft segment, and also has a high elastic modulus and an excellent pressure-sensitive adhesive property. For example, although applied to a thin polarizing plate on at least one surface of which a polarizer protective film is not used, the pressure-sensitive adhesive may allow the polarizing plate to exhibit excellent durability, moisture resistance, workability, a pressure-sensitive adhesive property and a light leakage inhibiting ability.
