Stress - strain isotherms and thermoelastic properties of crosslinked amorphous polyoxyethylene in compression
(Elsevier, 1975-05)
Stress-strain isotherms at a number of temperatures in the range 45-85[deg]C have been determined for a compressed, amorphous polyoxyethylene network swollen with a constant amount of non-volatile diluent. The observed ...
Curing reaction and product properties of polysulfones terminated with active functional groups
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
The curing processes of maleimide-terminated polyether sulfone oligomers ( M n from 1100 to 3000) and ethynyl-terminated polysulfone prepolymers ( M n from 2600 to 12000) were investigated by means of DSC. The ...
Gellan gum–O,O′‐bis(2‐aminopropyl)‐polyethylene glycol hydrogel for controlled fertilizer release
(Academic PressWiley Periodicals, Inc., 2018-01-10)
A gellan gum–Jeffamine superabsorbent hydrogel was obtained with different crosslink densities using different amounts of (1‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide hydrochloride) and N‐hydroxysuccinimide. Infrared ...
Volatile combustion products of polycarbonate and polysulfone
(Wiley Subscription Services, Inc., A Wiley Company, 1972-04)
Thermal analysis of polycarbonate and polysulfone has shown each plastic to undergo a two-step decomposition, the first step involving production of high-boiling chain scission and volatile products, the second resulting, ...
An investigation of the maximum experimental safe gap anomaly
(Elsevier, 1979)
The "safe gap" is defined as the maximum gap between two close-fitting, flat, machined metal surfaces that will just prevent an explosion within a vessel from producing a propagating combustion wave in the gases that ...
Synthesis and performance of a thermosetting resin: Acrylated epoxidized soybean oil curing with a rosin‐based acrylamide
(Wiley Periodicals, Inc., 2017-03-05)
A synthesized rosin‐based polymeric monomer, N‐dehydroabietic acrylamide (DHA‐AM), was introduced into an acrylated epoxidized soybean oil (AESO)/DHA‐AM system to afford a thermosetting resin through thermocuring. Different ...
On the dynamic structure factor, S(q,[omega]), of polymers in dilute solution
(Elsevier, 1981-08)
In principle, interpretation of dynamic scattering experiments requires theoretical calculation of either intermediate scattering functions S(q,t) or dynamic structure factors S(q,[omega]). Although dynamic scattering ...
Crosslinking chemistry for high-performance polymer networks
(Elsevier, 1994-11)
A new thermally reactive monomer has been designed and synthesized that brings novel crosslinking chemistry to high-performance polymers. This monomer (XTA) is a derivative of terephthalic acid and was based on the thermal ...
Determination of the electro-optical coefficient r33 and refractive index of para-substituted poly([gamma]-benzyl--glutamate) derivatives
(Elsevier, 1994-01)
The electro-optical coefficient r33 and refractive index of films of poly([gamma]-benzyl--glutamate) and the p-nitro, p-fluoro and p-trifluoromethyl derivatives were determined as a way to assess the non-linear optical ...
Microencapsulation of imidazole curing agent by solvent evaporation method using W/O/W emulsion
(Wiley Subscription Services, Inc., A Wiley Company, 2013-08-05)
The epoxy–imidazole resin system is used to form the anisotropic conducting film. The latent character of the system is very significant. In this study, imidazole (Im) or 2‐methylimidazole (2MI) was encapsulated for the ...
