composição adesiva sensível à pressão e fita sensível à pressão

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 monoolefinically 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.
