  • Abstract: The poly(methyl methacrylate)/silica nano-composite made from trimethoxysilyl functionalized poly(methyl methacrylate) and dimethyl diethoxysilane was newly prepared and its apatite-forming ability and mechanical properties were evaluated comparing to poly(methyl methacrylate)/silica nano-composite made from trimethoxysilyl functionalized poly(methyl methacrylate) and tetraethyl orthosilicate. (scientific.net)
  • Its high fracture toughness might come from the less quantity of siloxane linkages in its structure because dimethyl diethoxysilane had only two ethoxysilane groups while tetraethyl orthosilicate had four ethoxysilane groups. (scientific.net)
  • 22. A photovoltaic cell module as set forth in claim 1 wherein said tie layer is formed from a curable composition and said curable composition comprises at least one of an ethylene-vinyl acetate copolymer, a polyurethane, an ethylene tetrafluoroethylene, a polyvinylfluoride, a polyethylene terephthalate, and combinations thereof.

  • The documents referred to above use a volatile methyl siloxane fluid and a polydiorganosiloxane polyoxyalkylene copolymer. (justia.com)
  • They are used in many cosmetic products where eventual complete evaporation of the siloxane carrier fluid is desired. (wikipedia.org)
  • 8 . The method of claim 1 , wherein the polyelectrolyte materials are capable of attracting an amount of fluid at least about ten times the weight of the polyelectrolyte materials in their dry form under atmospheric pressure. (google.co.uk)
  • Its apatite-forming ability was similar to that of poly(methyl methacrylate)/silica nano-composite using tetraethyl orthosilicate but its fracture toughness was much improved. (scientific.net)
  • Microparticles which are less than 12 μm in size and are formed of or comprise a solid lipophilic group-containing compound having an HLB value less than about 20 produce a long lived ultrasonically echogenic entity in aqueous liquid and are useful as left heart ultrasonic contrast image enhancing agents.

  • 11. A contrast medium of claim 1, wherein the physiologically acceptable liquid vehicle is water, a physiological electrolyte solution, an aqueous solution of a mono- or polyhydric alcohol or of propylene glycol methyl ether, or an aqueous solution of a monosaccharide or a disaccharide. (google.es)
  • The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H(OSiH 2 ) n OH and (OSiH 2 ) n . Siloxanes also include branched compounds, the defining feature of which is that each pair of silicon centres is separated by one oxygen atom. (wikipedia.org)
  • However, as oligo methyl hydride siloxane is the water emulsion, it can be applied as an additive in the production of solutions and mixtures that is by the volumetric method. (wikipedia.org)
  • Coating industry: paint additives forming quick-drying, thermostable and water-resistant coats with constant gloss. (wikipedia.org)
  • This geometric consideration is the basis of the useful properties of some siloxane-containing materials, such as their low glass transition temperatures . (wikipedia.org)
  • These elements provide broad glass forming options when combined with the host matrix to allow for compositional tuning of properties. (spiedigitallibrary.org)
  • Aldehydes and siloxanes form methyl esters in a single step through mild oxidative esterification in the presence of a palladium catalyst or, alternatively, afford secondary alcohols via TBAF-promoted arylation in the absence of a catalyst at increased temperatures. (organic-chemistry.org)
