“…It was thought that C‐5 hydrocarbon resin had a good compatibility with polyisoprene phase instead of polystyrene phase. When excess resin was added, the polyisoprene phase was saturated and the polystyrene phase was strongly segregated from the polyisoprene phase 20. The homogeneity and microstructure of the matrix were destroyed obviously, which would significantly influence the performances of the patches, including the adhesive properties and drug release.…”

In this study, we conveniently obtained Ag(0)-polymer nanocomposites by reacting AgNO, with commercial poly(vinyl acetate) (PVAc) in the absence of a special reducing agent. The formation of Ag(0) metal was detected after formic acid (HCOOH) was added to a PVAc-AgNO3 complex system, and some of the acetate groups of the PVAc backbone were hydrolyzed to form hydroxyl groups (OH) under the catalytic effect of the reduced Ag(0) metal. Here, the structure of the partially hydrolyzed PVAc backbone was represented as PVOH-PVAc. X-ray diffraction spectra showed that the Ag(0) metal generated in this method was in the form of Ag crystals. The structure of the Ag(0)-polymer was analyzed by H-1-NMR and C-13-NMR spectroscopy. The micellization of the Ag(0)-polymer was also investigated by the addition of an inducing solvent to the formic acid solution of Ag(0)-polymer. The image showed that the morphology of the Ag micelles in the H2O-induced solvent was a Ag corona with a Ag shell, and that in the p-xylene induced solvent showed a Ag cluster core structure

“…[1][2][3][4][5][6][7][8][9][10] The styrenic block copolymers mainly include Styrenebutadiene-styrene (SBS) and Styrene-isoprene-styrene (SIS) copolymers. Historically, SIS copolymer has been widely utilized in the HMPSAs field because of its lower modulus, excellent compatibility with aliphatic tackifiers, lower viscosity, being less prone to gelation, and good selective tackification of the isoprene block.…”

In order to develop polarity-modulated hot-melt pressure-sensitive adhesives (HMPSAs), epoxidation of styrene-isoprene-styrene (SIS) copolymers, using in situ prepared per-formic acid was studied. The polymers were characterized with Fourier-transform infrared spectroscopy, 1 H nuclear magnetic resonance spectroscopy, differential scanning calorimetry, and contact angle tests. The epoxidation degree linearly increases with the epoxidation time without side reaction at low temperature. The polarity of the polymers increases with the epoxidation degree. At low epoxidation degree, the 180°peel strength of epoxidated-SIS-based HMPSA increases with the epoxidation degree. In epoxidated-SIS-based HMPSAs, ESIS plays the role of compatibilizer.
