Dupont’s Renewably Sourced High Performance Polymers
Renewably sourced, also commonly referred as biobased, materials are an integral part of DuPont’s commitment to sustainable growth. DuPont is a market leader in high performance renewably sourced polymers for engineering applications. These include products based on polyamide, polyester and thermoplastic elastomers and contain between 20 to 100 percent renewable carbon by weight. By tapping inn...
متن کاملHigh Performance Gel Permeation Chromatography of Polymers
The determination of the molecular weight distribution by gel permeation chromatography requires the establishment of a molecular weight calibration and efficient columns in order to minimise chromatogram broadening. The separation process is described in terms of steric exclu— sion, retardation and partial exclusion mechanisms in order to show how the universal calibration method may be influe...
متن کاملHigh-Performance Polymers Having Low Melt Viscosities
High-performance polymers that have improved processing characteristics, and a method of making them, have been invented. One of the improved characteristics is low (relative to corresponding prior polymers) melt viscosities at given temperatures. This characteristic makes it possible to utilize such processes as resin-transfer molding and resin-film infusion and to perform autoclave processing...
متن کاملPrepration and Characterization of Novel Ionoic Polymers to be Used as Artificial Muscles
The muscle-like technology would be of enormous advantages for biomedical applications such as medical implants and human assist devices. Ionic polymer metal composites (IPMCs) are one kind of biomimetic actuators. An ionic polymer metal composite composed from an ionomer with high ion exchange capacity that packed between two thin metal layers. In the present study we focused on the prep...
متن کاملSynthesis of Some Novel Tetrazole Substituted Benzimidazoles and Their Evaluation as Antioxidants
A series of tetrazole derivatives (3a-h) were synthesized and screened for antioxidant activity by nitric oxide free radical scavenging activity. All the synthesized compounds were structurally elucidated by spectral techniques such as IR, H NMR spectroscopy and mass spectrometry. The compounds 3b, 3d 3f and 3h exhibited promising antioxidant activities which were found to be comparable with st...
