    摘要: Disclosed is a composite pressure-sensitive adhesive comprising from about 95 to about 5 parts by weight of an acrylic pressure-sensitive adhesive; from about 5 to about 95 parts by weight of an at least partially soluble (in a solvent) polymer, and a compatibilizer present in the composite pressure-sensitive adhesive in an amount greater than 0 to about 10 parts by weight of the composite pressure-sensitive adhesive. The polymer is selected from the group consisting of a butadiene-containing polymer, an isoprene-containing polymer, a saturated olefin-containing polymer, and a styrene-containing polymer. The compatibilizer in the adhesive has a structure selected from the group consisting of (1) an acrylic adhesive-compatible segment and a polymer-compatible segment wherein at least a portion of the compatibilizer is present throughout either the acrylic adhesive, the polymer, or both, and (2) an acrylic adhesive-reactive segment and a polymer-compatible segment wherein at least a portion of the compatibilizer is present throughout the polymer.
