“…This morphology decreases the shear resistance of the emulsion adhesive because of the poor interconnections between the microgels and the linear polymers in the PSAs . Inherent properties, such as the copolymer composition and microstructure, molecular weight, and distribution are among the most influential parameters affecting the PSA properties . From the previously mentioned publications, to our knowledge, no studies reported in the literature have examined the application of a CTA on the high SC of acrylic PSAs by solvent polymerization.…”

In this study, we prepared high solid content (SC), solvent‐based, acrylic pressure‐sensitive adhesives (PSAs) with n‐dodecyl mercaptan as a chain‐transfer agent (CTA) and studied the crosslinking reactions between the crosslinker and the acrylic PSAs. Acrylic PSAs were prepared from 2‐ethyl hexyl acrylate, acrylic acid (AA), and 2‐azobisisobutyronitrile with a solution polymerization process. The results show AA resulted in an effective molecular weight in the acrylic PSAs, as it improved the hydrophilicity with increasing peel strength of the acrylic PSAs. As for the high SC, the molecular weight and system viscosity decreased through the addition of CTA. At a constant AA amount, the addition of CTA decreased the molecular weight and increased the hydrophobicity of the acrylic PSAs; this decreased the peel strength of the acrylic PSAs on the glass. Furthermore, the addition of CTA decreased the molecular weight and improved the acrylic PSAs' surface morphologies and optical properties. The acrylic PSAs produced in this study could meet production needs. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46257.

“…The balance between these three interrelated properties is usually tailored according to the end use of the PSA and the desired end-product properties [24]. The selection of monomers, initiator, chain transfer agent, emulsifiers, tackifiers and process parameters for synthesis affects the PSA microstructure [27], polymer average molecular weight and distribution [28][29][30][31] and copolymer composition [32], which are key PSA characteristics. The relative amount of the gel and sol polymer phase is also among the most important factors that influence the adhesive properties [25].…”

“…In this article, PUA hybrid emulsions were formulated using the semibatch emulsion polymerization method [23][24][25] with different concentrations of PU. In this emulsion, the isocyanate terminated PU polymers contained pendant carboxylic groups and methyl ethyl ketoxime end groups and the acrylic copolymers provide hydroxyl functionality.…”

Aqueous acrylic-polyurethane hybrid emulsions (PUA) were fabricated by semibatch emulsion copolymerization using a mixture of acrylic (AC) monomers in the presence of an isocyanate terminated polyurethane (PU). The effects of PU content on the morphology of the hybrid emulsions and film properties were here investigated in detail using FT-IR, UV, TEM, and SEM. TEM images clearly showed that hybrid emulsions exhibited a core-shell structure before neutralization. However, after neutralization with N,N-dimethylethanolamine, the typical particles exhibited phase inversion, producing particles with irregular hemispheres shapes and diameters about 0.5 lm. SEM images showed that the film surface became rougher as PU content increased, peaking at 10 wt %, the gloss of this film was 23.1 (60 ). The UV transmittance spectra of the PUA hybrid emulsion within a wavelength range 700-200 nm decreased as PU content increased. This was consistent with the changes in the surface roughness of the film. Electrophoresis took place on an aluminum alloy surface and the product was dried at 120 C. The film exhibited excellent mechanical performance due to curing reaction between the N@C@O group on PU and hydroxyl group on the AC copolymer. The gloss of the film was found to be as low as 4.0 after electrophoresis testing. These films may be useful in practical extinction electrophoresis. V C 2013 Wiley Periodicals, Inc. J. Appl. Polym.
