“…The peaks around 1067, 898 and 650 cm -1 can be identified for stretching vibrations of C-F in -CF 3 group [11]. The peak around 695 cm -1 can be attributed to C-F stretching and wagging vibrations in -CF 2 [12]. The peak appeared around 819 cm -1 is due to bending vibrations of Si-O bond.…”

“…This effect might have been relate to the coalescence in the latex particles and the increased gel content induced by self‐homopolymerization and the homopolymer of AMPS . The incomplete dispersion of unreacted emulsifier in the system caused by the reactive emulsifier AMPS also contributed to the increase in coagulum and the instability of polymerization . When the conversions decreased, the adhesive properties declined sharply.…”

A low-residual siloxane-modified polyacrylate pressure-sensitive adhesive (PSA) with a high peeling strength was prepared by seeded semicontinuous emulsion polymerization. 3-Glycidyloxypropyltrimethoxysilane was introduced into the acrylic (AC) PSA through a thermal posttreatment method to crosslink with AC. To improve the adhesion properties, a polymeric emulsifier, 2-acrylamido-2-methyl-1-propanesulfonic acid, was introduced into the system with the conventional emulsifier. Several key polymerization conditions, such as the initiator concentration, mass ratio of soft monomer to hard monomer, the content of polymeric emulsifier, and siloxane dosages were examined in detail. Then, the optimal conditions and a proper preparation process were established. The results show that we achieved not only a low repeeling residue with high tack and peeling strength but also excellent properties of high-temperature aging resistance and water resistance.

“…Because of their small size, fluorine atoms can shield a fluorinated carbon atom without any steric hindrance. 4,5 These polymers are applied to different surfaces and manufac-tured into thin films. 1 On the basis of these features, several improvements of the material properties can be expected.…”

“…[22][23][24][25][26][27][28][29] ATRP polymerizations of different types of fluorinated monomers [22][23][24][25][26][27][30][31][32][33][34] (usually acrylates and methacrylates) in either conventional solvents or supercritical carbon dioxide 28 were realized to obtain various polymer architectures with controlled molecular weights (MWs), polydispersities, terminal functionalities, and compositions. [40][41][42][43] Recently, the originally synthesized highly fluorinated fluoroalkoxy styrene monomers 2,3,5,6-tetrafluoro-4-(2,2,3,3,3-pentafluoropropoxy) styrene and 2,3,5,6-tetrafluoro-4- (2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluoroctaoxy) styrene were also used to produce polymers capable of forming low-surface-energy materials. 10,35 A number of monosubstituted styrenes, for example, 4-fluoromethylstyrene and 4-trifluoromethylstyrene, or styrenic fluorinated monomers have been polymerized by freeradical polymerization or ATRP.…”

A novel perfluorinated acrylic monomer 3,5-bis(perfluorobenzyloxy)benzyl acrylate (FM) with perfluorinated aromatic units was synthesized with 3,5-bis(perfluorobenzyl)oxybenzyl alcohol, acryloyl chloride, and triethylamine. Copolymers of FM monomer with methyl methacrylate (MMA) were prepared via free-radical polymerization at 80 C in toluene with 2,2 0 -azobisisobutyronitrile as the initiator. The obtained copolymers were characterized by 1 H-NMR and gel permeation chromatography. The monomer reactivity ratios for the monomer pair were calculated with the extended Kelen-Tüdos method. The reactivity ratios were found to be r 1 ¼ 0.38 for FM, r 2 ¼ 1.11 for MMA, and r 1 r 2 < 1 for the pair FM-MMA. This shows that the system proceeded as random copolymerization. The thermal behavior of the copolymers was investigated by thermogravimetric analysis and differential scanning calorimetry (DSC). The copolymers had only one glass-transition temperature, which changed from 46 to 78 C depending on the copolymer composition. Melting endotherms were not observed in the DSC traces; this indicated that all of the copolymers were completely amorphous. Copolymer films were prepared by spin coating, and contact angle measurements of water and ethylene glycol on the films indicated a high degree of hydrophobicity.
