Latest Patents

Barber's recent patents focus on a bulk polymerization process for free radical polymerization of vinyl monomers in a wiped surface reactor. This groundbreaking method allows for the combination of monomer streams with a free radical initiator to create a premix, which is then processed through a static mixer and into a wiped surface reactor. Notably, this reactor can be a counter-rotating twin screw extruder, enabling the production of polymer streams without solvents and with considerably reduced residence times compared to traditional solution or emulsion processes.

The patents detail the production of unique pressure-sensitive adhesive acrylate polymers, which are believed to exhibit a high degree of branching. This innovative bulk polymerization process facilitates the direct manufacture of adhesive articles by extruding them onto a substrate from the twin screw extruder, marking a significant advancement in the field.
