“…The chemical structure of some Schiff base monomers was discussed briefly using IR and 1 HNMR analyses in previous work. [23] In this respect, IR and 1 HNMR spectra were not recorded here for brevity. The formation of azomethine nitrogen in all compounds was concluded due to the appearance of strong band at 1600 cm À1 .…”

Six new surfactant blends were prepared by mixing one Schiff base non ionic surfactant prepared by etherification of Schiff base monomer with b,`b-dichlorodiethylether and PEG 400 in presence of NaOH with six water-soluble Schiff base nonionic surfactants prepared in the same way but etherified with PEG 2000. The mixing process was based on the high dehydration rates given by the PEG 400 Schiff base surfactant compared to the other PEG 2000 surfactants. The experimental results of this study indicate that the demulsification rates of these blends are higher than those of the PEG 400 surfactant. Demulsification process was carried out on an emulsion of w/o ratio 50:50 and studied at 60 C at two different concentrations of the demulsifiers (200 and 240 ppm). The dehydration rates of the six prepared blends reached 100%. The total dehydration time varied from 50 minutes up to 2 hours.

“…Epoxy resins, one of the most important classes of thermosetting polymers, have gained extensive applications in many fields of technology and daily life, such as matrices, structural adhesives, coatings and microelectronics due to their outstanding properties including high dimensional stability, good mechanical property, excellent chemical resistance, good thermal resistance, high electrical resistance and strong adherence to many substrates [15][16][17][18][19]. Some fluorine-containing epoxy resins have been synthesized and their physicochemical properties have been studied by several researchers.…”

Synthesis and surface properties of semi-interpenetrating fluorine-containing polyacrylate and epoxy resin networks

et al. 2012

Semi-interpenetrating polymer networks (SemiIPNs) based on fluorine-containing polyacrylate and epoxy resin were synthesized by the simultaneous polymerization of fluorine-containing acrylate and epoxy resin. Fourier transform infrared (FTIR) spectrometry and X-ray photoelectron spectroscopy (XPS) analyses proved that the fluorine-containing groups have been introduced into Semi-IPNs successfully. In addition, XPS analysis intuitively showed that the fluorine content of the film-air interface of the interpenetrating fluorine-containing polyacrylate and epoxy resin networks (FPAER-SIPNs) film was much higher than that of the film-glass interface. It is noted that the introduction of fluorine-containing groups significantly improved the hydrophobic property of polymer networks. Moreover, when the fluorine content increased, the contact angle of water on FPAER-SIPNs film was increased obviously and the water uptake was decreased gradually. These results indicated that introducing fluorine-containing groups to SIPNs has potential advantage for improving the surface properties of epoxy resin.

“…Epoxy resins are widely used in the electronic industry, advanced composites, coatings, structural adhesives, paints, varnishes, construction materials, and some other advanced fields because of their superior thermal, mechanical and electronic properties like high stiffness, high strength, good impact resistance, dimensional stability, etc 1–9. Epoxy resins are real polyethers based on a condensation reaction between epichlorhydrin and dian (the most common is bisphenol A).…”

The chemical modification of the structure of the unsaturated polyester obtained in poly condensation process of 1,2,3,6-tetrahydrophthalic anhydride, maleic anhydride, and ethylene glycol by well known conventional method of epoxidation with peracetic acid in mild conditions has been presented. The new material containing both epoxy groups and unsaturated double bonds in polyester chain was characterized by FTIR and 1 H NMR spectra. The prepared unsaturated epoxy polyester was suitable material for further chemical modification. Both epoxy groups and unsaturated double bonds can be used as cross-linking sites. Curing behavior, thermal, and viscoelastic properties of the unsaturated epoxy polyester cured with different hardeners: 1,2,3,6-tetrahydrophthalic anhydride (THPA), hexahydrophthalic anhydride (HHPA), and/or with vinyl monomer (styrene) using radical initiator-benzoyl peroxide (BPO) were studied by differential scanning calorimetry (DSC), thermo gravimetric analysis (TGA), and dynamic mechanical analysis (DMA).
