Pressure sensitive adhesive compositions |
| 摘要 |
A pressure-sensitive adhesive composition having excellent tackiness and improved thermal resistance comprises (A) a low molecular weight polyisoprene, which may be obtained by polymerizing isoprene monomer with the aid of a lithium-type catalyst, said polyisoprene having a cis-1,4 content of not less than 75%, a viscosity average molecular weight of 8,000 to 77,000 and an Mw/Mn value (Mw: weight average molecular weight; Mn: number average molecular weight) of 1.0 to 2.7 and (B) an elastomer.
