“…For removable PSA tapes applications, the 180° peel strength should be lower than 160 N/m, while the tack should be more than 7 #, and the shear holding power should be more than 72 h. All the above parameters are the requirements in removable PSAs area . Polyacrylate emulsions are often coated on carrier of polypropylene (PP) to obtain the PSA tapes, which has been commonly used in our daily life . While, some problems still exist.…”

In the area of pressure sensitive adhesives (PSAs), corona treatment or other preprocessing on the carrier was commonly utilized for the enhancement of the interaction between the adhesive layer and the carrier, with complicated procedures and operations. To make it easy, one-pot emulsion polymerization using n-butyl acrylate, isobornyl methacrylate (IBOMA), 2-hydroxyethyl acrylate and acrylic acid was conducted in the presence of a reactive emulsifier SR-20 to obtain a reinforced adhesive tape. First, the emulsion had good stabilities, especially freeze-thaw stability, which was helpful to the fabrication of PSAs. Second, IBOMA increased the binding strength between adhesive layer and adherend. The properties of the final tapes well fulfilled the requirements of this areas, such as that the 1808 peel strength of 125.9 N/m when coated on non-corona surfaces, the tack of 19 #, and the shear holding time of more than 100 h. Third, the tapes produced using the above emulsion could be removed many times, with no PSAs residue on the adherend even when coated on untreated PP, which showed the potential of recycling and environmental protection. Thus, these properties make the polyacrylate emulsion have great potential for practical applications.

“…In general, the glass transition temperature (T g ) of PSAs should be lower than room temperature. There are only several acrylic monomers used for PSAs, such as butyl acrylate (BA) and 2-ethylhexyl acrylate (EHA) [7][8][9].…”

“…Emulsion acrylic copolymers have enjoyed the fastest growth and the biggest share of the PSA market in commercial applications 2, 3. Among acrylic polymers making for PSAs, long‐alkyl acrylates, such as poly( n ‐butyl acrylate), poly(BA),4–15 and poly(2‐ethyl hexyl acrylate), poly(2‐EHA)2, 4, 15–21 are generally used. However, because these kinds of acrylic PSAs comprise polymers that have high entanglement molecular weight ( M e ) values,22 low glass‐transition temperature ( T g ) values, and medium to low molecular weights, this may present a problem in PSA label converting and high temperature printing, and some types of crosslinking must be provided to yield shear holding power 15, 22–26.…”

In the past work, the shear resistance of pure poly(n-butyl acrylate) was low, even incorporation of inorganic filler, silica in the composition. It is well-known that the copolymerization of n-butyl acrylate (BA) with methyl methacrylate (MMA) will increase the glass transition temperature, and enhance the shear resistance of acrylic polymers. In the current work, the preparation of a series of acrylic water-borne pressure-sensitive adhesives (PSAs) with the controlled composition and structure for the copolymerization of BA and acrylic acid (AA) with different MMA contents, poly(BA-co-MMA-co-AA) was reported and its effects on adhesive properties of the latices were investigated. The latices of poly(BA-co-MMA-co-AA) were prepared at a solid content of 50% by two-stage sequential emulsion polymerization, and this process consisted of a batch seed stage giving a particle diameter of 111 nm, which was then grown by the semicontinuous addition of monomers to final diameter of 303 nm. Dynamic light scattering (DLS) was used to monitor the particle diameters and proved that no new nucleation occurred during the growth stage. Copolymerization of BA with MMA raised the glass transition temperature (T g ) of the soft acrylic polymers, and had the effect of improving shear resistance, while the loop tack and peel adhesion kept relatively high. The relationship between pressuresensitive properties and molecular parameters, such as gel content and molecular weight, was evaluated.
