these polymers may include further comonomers, which advantageously are polymerizable with the at least one acrylic monomer, as for instance vinyl compounds having functional groups, maleic anhydride, styrene, styrenic compounds, vinyl acetate, acrylamides, double-bond-functionalized photo-initiators, and...
This study focuses on the synthesis of zinc and copper oxide nanoparticles using green methods by plant extracts. The resulting metal oxides were analyzed using FT-IR spectroscopy, TGA, TEM, zeta potential and assessed for their efficacy as pigments base
silicone elastomer comprising at least one polyorganosiloxane having the formula: ##STR1## where R is hydrogen or substituted or unsubstituted alkyl, alkenyl or aryl having less than 19 carbon atoms, each of A and D may be any of methyl, hydroxy or vinyl groups, 0<m/n≤1 and m+n>...
In order to obtain superhydrophobic surface coatings on metal substrates, low surface energy chemical materials and nanoscale particles are necessary to add to the gels. Fan et al. [66] reported the use of a simple sol-gel method by utilizing the hydrolysis of vinyltrimethoxylsilane (VTMS) to...
To be used as diesel fuel, the vinyl content in non-polar phase should be reduced because double bonds are not favorable during combustion as it affects ignition delay time and combustion emission [62]. Methyl composition was predominant chemical bond in non-oxygenated fractions and comprised ...
Fouling of heat exchangers (HEs) has become a major concern across the industrial sector. Fouling is an omnipresent phenomenon but is particularly prevalent in the dairy, oil, and energy industries. Reduced energy performance that results from fouling re
[0034] (9) vinyl ketones, such as methyl vinyl ketone, ethyl vinyl ketone, propyl vinyl ketone and phenyl vinyl ketone; [0034] [0035] (10) olefins, such as ethylene, propylene, isobutylene, butadiene and isoprene; [0035] [0036] (11) N-vinylpyrrolidone, N-vinylcarbazole, 4-vinylpyridine,...
include vinylpyridine, vinylimidazole, triaminofunctionalized styrene (for example, 4-(N,N-dimethylamino)-styrene(DMAS), 4-(N,N-diethylamino)-styrene (DEAS)), cyclic or acyclic ethylenically unsaturated amides (for example, N-vinylpyrrolidone, N-vinylcaprolactam, N-vinylholomamide, and (meth)...
chromium, cobalt, tin, gold and silver. From the viewpoint of excellent corrosion resistance to the material used in the sol production step described later, a simple substance such as titanium, gold and silver, iron and aluminum on which an oxide film is formed can be used as the metal....
urea resins, acrylic resins, polyamide resins, and so on. Particularly preferred are polyurethane resins which contain a urea bond or urethane bond in their structures. These resins may all be used either singly or in combination, in the form of either solution or dispersion in an organic solv...
