and single phase melt processible rubber (MPR), future developments and potential for TPEs; and a summary and course review.
Today, the cements most widely used to cement molar bands are conventional glass ionomers
(CGI), which have significant advantages, such as constant fluoride release and uptake, microbial inhibition, chemical adhesion to teeth and to metal, (5-10) low thermal coefficient of expansion (6) and low solubility.
Specifically, disclosed are methods and products resulting therefrom for creating functionalized ionomers
and grafting polyamide to halobutyl ionomers
via reactive extrusion.
The second volume is devoted to aspects of applications, among them, fluoroalkyl acrylate polymers and their applications, fluoroplastics and fluoroelastomers: basic chemistry and high-performance applications, the commercial synthesis and applications of poly(vinylidene fluoride), fluoridated ionomers
membranes: monomer and polymer synthesis and applications, and fabricating flexible transparent nanohybrids with heat-resistant properties using a fluorinated crystalline polymer.
Hence, various antimicrobials have been added to glass ionomers
to combat the residual bacteria.
Effects of temperature on the fluoride release and recharging ability of glass ionomers
3) Sealants are also effective when placed over incipient lesions, due to the fluoride release of glass ionomers
and some resin materials.
are partially crosslinked ionomeric resins, and perform in peelable seal applications through delamination of the seal/seal interface.
are polymers that contain a small number of ionic salt groups attached to hydrophobic organic backbone chains.
Composites modified by the addition of polyacids (or compomers) will not be discussed in this article because these are more similar to composites than glass ionomers
Early and long-term wear of conventional and resin-modifed glass ionomers
