Polymer-Solvent Interaction Parameter of Ethylene Propylene Terpolymer

A solution blending route to ethylene propylene diene terpolymer/layered double hydroxide nanocomposites

Ethylene propylene diene terpolymer (EPDM)/MgAl layered double hydroxide (LDH) nanocomposites have been synthesized by solution intercalation using organically modified LDH (DSLDH). The molecular level dispersion of LDH nanolayers has been verified by the disappearance of basal XRD peak of DS-LDH in the composites. The internal structures, of the nanocomposite with the dispersion nature of LDH ...

Influence of solvent/polymer interaction on miscibility of PMMA/PCL blend: thermal analysis approach

propylene glycol , and ethylene glycol - based antifreeze

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 ...

Controlled actuation of Nafion-based Ionic Polymer-metal Composites (IPMCs) with Ethylene Glycol as Solvent

Ionic polymer-metal composites (IPMCs) consist of a perfluorinated ionomer membrane (usually Nafion or Flemion). The ionomer is plated on both faces with a noble metal such as gold or platinum. It is neutralized with a certain amount of counterions that balance the electrical charge of anions covalently fixed to the backbone membrane. IPMCs are electroactive materials that can be used as actuat...

On 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...
