    摘要: A pressure-sensitive adhesive composition based on liquid rubber, a cross-linking agent therefor and a tackifier, in which the liquid rubber component is a modified low molecular weight polyisoprene which is obtainable by adding 0.03 to 7 mol % of maleic anhydride or a derivative thereof, based on each isoprene monomer unit, to a low molecular weight polyisoprene having a molecular weight in the range of 10,000 to 90,000 is useful in producing a pressure-sensitive adhesive composition having very desirable tackiness, cohesive force and bonding characteristics without use of an organic solvent or with use of only a small amount of the solvent.
