ADHESIVES COMPRISING CROSSLINKER WITH (METH)ACRYLATE GROUP AND OLEFIN GROUP AND METHODS

摘要

There is provided an article having a release liner and a pressure sensitive adhesive composition disposed along a major surface of the release liner, where the pressure sensitive adhesive composition has at least 50 wt-% of polymerized units derived from alkyl meth(acrylate) monomer(s); and 0.2 to 15 wt-% of at least one crosslinking monomers comprising a (meth)acrylate group and a C6-C20 olefin group, the olefin group being optionally substituted. In another embodiment, an adhesive composition is described comprising a syrup comprising i) a free-radically polymerizable solvent monomer; and ii) a solute (meth)acrylic polymer comprising polymerized units derived from one or more alkyl(meth)acrylate monomers; wherein the syrup comprises at least one crosslinking monomer or the (meth)acrylic solute polymer comprises polymerized units derived from at least one crosslinking monomer, the crosslinking monomer comprising a (meth)acrylate group and a C6-C20 olefin group, the olefin group being optionally substituted.
