Resultant synergism in the shear resistance of acrylic pressure‐sensitive adhesives prepared by emulsion polymerization of n‐butyl acrylate/2‐ethyl hexyl acrylate/acrylic acid

Abstract: Acrylic emulsion pressure-sensitive adhesives (PSAs) were synthesized by the copolymerization of n-butyl acrylate with various levels of 2-ethyl hexyl acrylate (2EHA) and a small constant amount of acrylic acid. The effect of varying the n-butyl acrylate/2EHA monomer composition on the kinetic behavior of the polymerization and the characteristics of the copolymers prepared in a batch process were investigated. The results showed that increasing the amount of 2EHA in the monomer caused the polymerization rate … Show more

“…Acrylate copolymers are of specific interest because of their widespread use in coatings, adhesives, resins, and many other products [1,2]. N-Butyl acrylate (BA), 2-ethyl hexyl acrylate (EHA), and methyl methacrylate (MMA) monomers are used in adhesive production and coating applications as binders in household paints [2,3] largely because their different glass transition temperatures allow for the control of adhesive and other mechanical properties [4,5].…”

“…Mainly, there should be a balance between viscous and elastic properties of PSAs. It should also be considered that PSAs have to pass contradictory requirements under different stress rates; at low shear rates, PSAs must flow (bonding) ( Figure 6) and at high peeling rates there should be an elastic response (debonding) [6,[10][11][12].…”

“…Despite of its outstanding performance, application of solution PSAs have gradually decreased because of its economic reasons and environmental restrictions. In contrast, emulsion PSAs, especially acrylate emulsion, has been widely researched for its environmental safety, optical clarity and low cost [4][5][6]. In general, the glass transition temperature (T g ) of PSAs should be lower than room temperature.…”
