Electromechanical Properties of Ethylene Propylene Diene Elastomers: Effect of Ethylene Norbornene Content
Ethylene propylene diene elastomers (EPDM) of various side chains and molecular weights were prepared as thin discs and the effects of electric field strength and temperature on the electromechanical properties were investigated. The electrical conductivity, the dielectric constant, the storage and loss moduli (G and G), the storage modulus response ( 1000V mm G ), and the storage modulus ...
متن کاملUltrasonic and volumetric study of aqueous solution of ethylene glycol, propylene glycol in iso-propanol
Ultrasonic velocities, u, and densities, ρ of 0.5 m, 1.0 m and 1.5 m aqueous ethylene glycol and propylene glycol solutions in iso-propanol have been measured over the entire composition range at 308.15 K. From this experimental data, deviation in ultrasonic velocity, ∆u, deviation in isentropic compressibility, ∆ks, excess intermolecular free length, E f L , excess acoustic impedance, Z E and ...

of AF performance. that contain EG has been reponed to result in irreversible damage to renal, hepatic, cardiovascular, and central nervous systems, and is a cause of death in household pets and other animals.2-4 It is not known why some animals ingest EGcontaining products. Although there are reports suggesting that the "sweet" taste of EG, and of products containing it, may lead to ingestion ...
متن کاملOn the Configurational Statistics of Ethylene-Propylene Copolymers
Mean-square unperturbed dimensions {r2)0 and their temperature coefficient d In{r2)0/dT have been calculated for ethylene-propylene copolymers by means of the rotational isomeric state theory of chain molecules. Conformational energies required in the analysis are shown to be readily obtained from previous analyses of polyethylene and polypropylene, without additional approximations. Results th...
متن کاملAn Integrated AHP-PROMETHEE Method for Selecting the most Suitable Ethylene Propylene Diene Termonomer
This paper considers the problem of selecting the most appropriate ethylene propylene diene monomer (EPDM), which is a polyolefin with a variety of usages in different areas. The metallocene catalyst, bis(2-phenyl indenyl) zirconium dichloride ((2-PhInd)2ZrCl2) was synthesized by a modified method and applied to the terpolymerization of ethylene, propylene, and 5-ethylidiene-2-norbornene (ENB)....
