摘要： The present invention relates to a method of making a self-stick foam adhesive, comprising a. a crosslinked (meth)acrylate polymer comprising repeating units derivable from a monomer composition comprising iv. 55 to 97.4 wt. % of one or more alkyl (meth)acrylate monomers, the alkyl groups of which comprise from 4 to 14 carbon atoms v. 2.5 to 40 wt. % of one or more ethylenically unsaturated monomers comprising a nitrogen- or oxygen containing heterocyclic ring vi. 0.1 to 5 wt. % of one or more polar comonomers b. 1 to 60 parts by weight of one or more hydrogenated resin tackifier per 100 parts by weight of the cross-linked (meth)acrylate polymer and c. 1 to 20 parts by weight microspheres per 100 parts by weight of the cross-linked (meth)acrylate polymer, the method comprising polymerizing monomer components of the monomer composition and wherein at least part of the polymerization is carried in the presence of crosslinking agent, the total amount of crosslinking agent used in the polymerization being between 0.01 and 2 parts by weight per 100 parts by weight of the monomer composition, 1 to 60 parts of one or more hydrogenated resin tackifier per 100 parts by weight of the monomer composition and 1 to 20 parts microspheres per 100 parts of the monomer composition and wherein the polymerization is initiated by radiation substantially in the absence of solvent. The present invention also relates to a self-stick foam adhesive obtainable by such method.
