Ambient Polymerization of Acrylic Pressure Sensitive Adhesives
Traditional solution acrylic polymers for pressure sensitive adhesives (PSA) are synthesized using conventional free radical initiation systems based upon organic peroxide or azo compounds 1 . Such syntheses are heat activated and employ solvent reflux temperatures during the polymerization process. The resulting acrylic polymers are formed with a relatively broad molecular weight distribution ...
متن کاملWaterborne polyurethane-acrylic hybrid nanoparticles by miniemulsion polymerization: applications in pressure-sensitive adhesives.
Waterborne polyurethane-acrylic hybrid nanoparticles for application as pressure-sensitive adhesives (PSAs) were prepared by one-step miniemulsion polymerization. The addition of polyurethane to a standard waterborne acrylic formulation results in a large increase in the cohesive strength and hence a much higher shear holding time (greater than seven weeks at room temperature), which is a very ...
متن کاملPickering Emulsion Polymerization of Styrene-co-butyl Acrylate Nanoparticles by Using Cloisite Na+ as Surfactant
Cloisite Na+was used as a solid surfactant (stabilizer) in Pickering emulsion polymerization of styrene-co-butyl acrylate in presence of oil soluble initiator, azobisisobutyronitrile (AIBN) and water soluble initiator, potassium persulfate (KPS). Fourier transform infrared (FTIR) spectrum approved the corporation of Cloisite Na+ layers within the polymer matrix. Effect of clay content was a...

15 صفحه اولMiniemulsion polymerization of acrylated methyl oleate for pressure sensitive adhesives
The focus of this work was to improve the aqueous emulsion polymerization of a highly water-insoluble monomer derived from plant oil, acrylated methyl oleate. Conventional emulsion polymerization requires excessive amounts of surfactant and long reaction time. Miniemulsion polymerization improved the polymerization significantly. Only a fraction of the surfactant and reaction time that was nece...
