“…The peaks at 911 and 836 cm −1 were also attributed to epoxide band; these bands may conclude that the epoxy group had been introduced into the system. 23,34 Strictly speaking, these spectra and the aforementioned ones may confirm and prove that the epoxy resin (EC157) has been completely introduced in the system.…”

“…Therefore, as shown in Figure (b), the mixture comprising the linear PMMA polymer which prepared from the monomers with contents of epoxy resin could develop a thin continuous interior shell along with different thicknesses and a thicker rough exterior wall. It has been reported that this continuous layer can be formed also from the reaction of epoxy and MMA at the first stage . The variation in shell thickness, which is clearly shown in Figure (b), could be attributed to the relatively hard outer surface of the droplets.…”

Encapsulated epoxy resin healing agents with poly(methyl methacrylate (PMMA) as a thermoplastic polymeric shell are suffered from leakage of the core after a while. This problem leads to loss of their performance and its ability in self‐healing systems. One way to stop or reduce the leakage of the core is crosslinking the PMMA shell. In this study, nanoencapsulation of epoxy healing agent with crosslinked PMMA as shell was carried out by in situ polymerization via phase inversion emulsion method. Ethylene glycol dimethacrylate was employed as crosslinking agent. Nonionic (SPAN 60) and ionic (sodium dodecyl sulfate) surfactants were used for competitive adsorption and phase inversion in emulsion system. Chemical structures, morphologies, and thermal properties of nanocapsules were characterized by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, differential scanning calorimetry, and thermogravimetric analysis, respectively. SEM investigations showed that nanocapsules had a particle size of less than 100 nm with a narrow particle size distribution. Efficiency of nanoencapsulation was equal to 83.5%. And synthesized nanocapsules had at least 37% core contents. Nanocapsules with crosslinked shell were able to maintain liquid core up to 18 weeks, while, noncrosslinked shell lost core content after 14 weeks. It seems that low crosslink density has no effect on capsule durability. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48793.

Reactive pressure‐sensitive adhesives (PSA) have to meet the requirements for sufficient tack prior to crosslinking but also high shear after crosslinking. This article examines the use of secondary acrylic dispersions with reactive groups and epoxy resin dispersions for such PSA. Long‐term stable secondary PSA dispersions with high tack after film formation were obtained. Tack was dependent on the amount of carboxylic acid groups in the polymer as well as the base used for partial neutralization of the solvent‐borne copolymers. Reactive PSA were prepared by mixing a secondary dispersion with high amounts of carboxylic acid groups with an epoxy resin dispersion providing no tack. Variation of mixing ratio gave reactive PSA with sufficient tack, peel, and shear prior to crosslinking. Crosslinking of these reactive PSA at elevated temperatures led to high shear which was limited by incomplete molecular mixing of both phases. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
