PURPOSE: An adhesive composition is provided to have excellent loop adhesion, 180°release strength, softening point, etc by comprising asymmetrical block copolymer. CONSTITUTION: A taper block copolymer is in chemical formula 1: A1-(A2/B)-A3. In chemical formula 1, A1 and A3 is vinyl aromatic block polymer, A2 is vinyl aromatic monomer, B is conjugated diene monomer, (A2/B) is copolymerized taper block copolymer, and the block size of A1 and A3 are not same. An adhesive composition comprises 100.0 parts by weigh of the taper block copolymer, 100-400 parts by weight of an adhesive resin, 10-200 parts by weight of plasticizer, and 0.1-10 parts by weight of a stabilizer. |
