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.
