    摘要： The present disclosure generally relates to conformable adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles. In some embodiments, the adhesive article includes (1) a releasable layer having a first major surface and a second major surface; the second major surfaces including a pressure sensitive adhesive capable of adhering the adhesive article to a surface; and (2) a compliant layer having a first major surface and a second major surface; the second major surface of the compliant layer adjacent to the first major surface of the releasable layer. In some embodiments, the releasable layer debonds from both the surface and the compliant layer when the adhesive article is stretch released at an angle of less than 35 degrees.

    摘要： A pressure sensitive adhesive composition is described comprising 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. In yet other embodiments, methods of preparing adhesive compositions are described

    摘要： Pressure-sensitive adhesives that have good performance characteristics under typical use conditions and that later can be degraded and/or removed readily under basic conditions are provided. More specifically, the pressure-sensitive adhesives contain a copolymeric (meth)acrylic-based elastomeric material prepared from a polymerizable material that contains a (meth)acrylate monomer having both a (meth)acryloyl group plus an ester linkage that is not part of a (meth)acryloyl group.
