摘要：
A pressure-sensitive adhesive composition is disclosed. The composition comprises a particulate polymer of a monomer mixture comprising (a) an alkyl (meth)acrylate monomer; (b) at least one of (b−1) an alkyl (meth)acrylate monomer with the alkyl group having a carbon number of 15 to 24 and the alkyl group being a linear alkyl group and (b−2) an alkyl (meth)acrylate monomer with the alkyl group having a carbon number of 15 to 24 and the alkyl group being a branched alkyl group; and (c) a monoolefmically unsaturated monomer having a ketone group with the alkyl group having a carbon number of 8 to 14. Pressure sensitive adhesive tapes incorporating such adhesive compositions are also described.
