“…Butyl acrylate (as well as methyl ester, ethyl ester, and 2-ethylhexyl ester) belongs to the soft monomers. It can be copolymerized, cross-linked, and grafted with a variety of hard monomers to synthesize acrylates . Hard monomers include methyl methacrylate, styrene, acrylonitrile, and ethylene vinyl acetate.…”

Adhesion and agglomeration of small sticky particles, i.e., microstickies, onto paper and paper machines cause serious problems for recycling mills. Because associations between materials with similar surface energies are strongest, we propose an "adhesives collect stickies" strategy to physically remove microstickies from whitewater systems. We characterized deposits from a commercial paper machine and observed a large amount of acrylate-based materials. Based on this observation, we chose to graft glycidyl methacrylate (GMA) to surfaces of polypropylene (PP) to make it more similar to the deposited stickies, which will encourage association by van der Waals forces and interdiffusion. The modified material efficiently collected acrylic adhesive particles suspended in water (58.3%) and particles found in paper mill whitewater (40.6%). Additionally, a flow cell incorporating layers of modified mats of fibers shows good efficiency (40.6−49.4%) for collecting stickies at steady flow rates. This strategy may provide a method for removing microstickies without disturbing the chemical environment of the papermaking system.
