  • Pressure sensitive adhesives and articles including radial block and acrylic polymers
    Patent number: 6503621
    Abstract: Pressure sensitive adhesive compositions and articles, wherein the adhesive includes at least one acrylate pressure sensitive adhesive component and at least one thermoplastic elastomer-based pressure sensitive adhesive component. The acrylate component includes at least one polymerized monofunctional (meth)acrylic acid ester monomer having a Tg of no greater than about 0° C. when homopolymerized, and 0 to about 10 wt % of at least one copolymerized monofunctional ethylenically unsaturated monomer having a Tg of at least about 10° C. when homopolymerized. The thermoplastic elastomer-based pressure sensitive adhesive component includes a radial block copolymer.
