    Abstract: Masking tapes that changes color when the tape is rubbed down or dispensed onto an adherend and methods of making such tapes are disclosed herein. The tape includes a backing, a layer of adhesive on the bottom surface of the backing, and a release structure on the top surface of the backing that includes a pressure-chromic indicator and a release layer. The pressure-chromic indicator is characterized in that it is not activated by the pressure applied during the manufacturing process, but is activated by the pressure applied when the tape is rubbed or dispensed onto an adherend.

    Abstract: A method for continuous bulk polymerization is disclosed that includes providing a planetary roller extruder having a plurality of planetary roller zones, introducing an acrylate monomer, a di-vinyl monomer, and a hydroxyl functional acrylic monomer into the planetary roller extruder, introducing an initiator into the planetary roller extruder for initiation of a free-radical polymerization of the acrylate monomer, the di-vinyl monomer, and the hydroxyl functional acrylic monomer to form an acrylic polymer, maintaining the temperature of the free-radical polymerization in the planetary roller extruder below 240° C., and discharging a portion of the acrylic polymer from the planetary roller extruder, and returning the portion of the acrylic polymer to one or more of the plurality of planetary roller zones.
