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 کاملEffect of Monomer Composition on Adhesive Performance for Waterborne Acrylic Pressure-Sensitive Adhesives
A series of pressure-sensitive adhesives (PSAs) with different monomer composition was prepared using emulsion polymerisation. The monomers were butylacrylate (BA), 2-hydroxyethyl acrylate (2-HEA), acrylic acid (AA) and 2-ethylhexyl acrylate (2-EHA). The adhesive performance was studied at 4%, 8% and 12% 2-EHA content based on total monomer (BOTM) composition. The adhesives obtained with consta...
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 کاملpH dependence of the properties of waterborne pressure-sensitive adhesives containing acrylic acid.
Polymer colloids are often copolymerized with acrylic acid monomers in order to impart colloidal stability. Here, the effects of the pH on the nanoscale and macroscopic adhesive properties of waterborne poly(butyl acrylate-co-acrylic acid) films are reported. In films cast from acidic colloidal dispersions, hydrogen bonding between carboxylic acid groups dominates the particle-particle interact...
متن کاملProperties of solvent-borne acrylic pressure-sensitive adhesives synthesized by a simple approach
Acrylic polymers are widely used for fabricating pressure-sensitive adhesives (PSAs) with the inherent unique advantages of transparency and superior intrinsic adhesive properties over other polymer-based adhesives. In this study, we have developed and evaluated a method of obtaining by radical copolymerization PSAs for liquid crystalline (LCD) applications. Various factors including the amount...
