20090048407 | RECIRCULATION LOOP REACTOR BULK POLYMERIZATION PROCESS - A process for producing polymer and more particularly adhesive using a recirculating loop reactor. In one embodiment the reactor includes one or more mixers to mix feed stock with the polymerized material recirculating in the reactor. In another embodiment a planetary roller extruder (PRE) may be used for this purpose. In still another embodiment, a combination of one or more static mixers and one or more PREs may be used. | 02-19-2009 |
20090280301 | EDGE COATINGS FOR TAPES - Disclosed is a tape including a substrate having an adhesive layer applied thereto and an edge coating. The substrate and the adhesive together provide at least one masking edge where the edge coating is applied. The edge coating includes a lipophilic agent, a flocculating agent, or combinations thereof. The edge coating provides the tape with enhanced masking ability by preventing paints, varnishes, paint strippers, and other coating compositions from infiltrating the tape substrate or the interface between the tape and an adherend. | 11-12-2009 |
20100105847 | PLUG FLOW BULK POLYMERIZATION OF VINYL MONOMERS - A process for continuous bulk polymerization is disclosed that includes providing a plug flow reactor comprising a primary loop reactor including a loop for recirculating a portion of a polymer-in-progress at a polymer flow rate back to a reactor in the primary loop reactor, introducing at least one monomer into the primary recirculation loop reactor at a monomer flow rate, polymerizing the monomer in the primary recirculation loop reactor in the presence of an initiator by way of a free-radical polymerization to form a polymer-in-progress, and recirculating a first portion of the polymer-in-progress through the loop into a reactor in the primary loop reactor to combine with the monomer at a ratio of polymer flow rate to monomer flow rate that is greater than 5. | 04-29-2010 |

20140134407 | EDGE COATING FOR TAPES - Disclosed is a tape including a substrate having an adhesive layer applied thereto and an edge coating. The substrate and the adhesive together provide at least one masking edge where the edge coating is applied. The edge coating includes a flocculating agent. The edge coating provides the tape with enhanced masking ability. | 05-15-2014 |
20140144801 | MEMBER FOR USE IN UNDERSEA APPLICATIONS - A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing | 05-29-2014 |
20140299055 | Edge Coating for Tapes - Disclosed is a tape that includes a substrate having an adhesive layer applied thereto, and an edge coating applied to a masking edge of the tape. The substrate and the adhesive, together, define a first and a second masking edge of the tape. The edge coating includes a flocculating agent that is a polyvalent metal salt or an ionic polymer. The edge coating improves the ability of the tape to provide a sharp mask line after a paint, a varnish, a paint stripper, or other coating composition is applied to a surface where the tape is adhered. | 10-09-2014 |
20150152207 | CONTINUOUS BULK POLYMERIZATION OF VINYL MONOMERS - 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. | 06-04-2015 |
