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 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...
متن کاملSkin Development during the Film Formation of Waterborne Acrylic Pressure-Sensitive Adhesives containing Tackifying Resin
Tackifying resins (TR) are often used to improve the adhesive properties of waterborne pressure-sensitive adhesives (PSAs) derived from latex dispersions. There is a large gap in the understanding of how, and to what extent, the film formation mechanism of PSAs is altered by the addition of TR. Herein, magnetic resonance profiling experiments show that the addition of TR to an acrylic latex cre...
