Abstract:
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 styrene-containing 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 compatibilizer having 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 substantially 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 substantially throughout the polymer.
