The influence of the water soluble non-ionic tri-block copolymer PEO-PPO-PEO [poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)] i.e., E2P16E2 (L31) on the microstructure and self-aggregation dynamics of the anionic surfactant sodium dodecylsulfate (SDS) in aqueous solution was investigated using cloud point (CP), isothermal titration calorimetry (ITC), high resolution nuclear mag...

In this paper, we present the results of dispersion thermodynamically immiscible polypropylene (PP) and ethylene-propylene triple synthetic rubber (EPTSR) polymer blends using Solution-Enhanced Dispersion by Supercritical Fluid (SEDS) technique at operation conditions in pressure range (8 to 25) MPa temperatures t = 40 °C 60 °C. The kinetics crystallization phase transformation obtained convent...

Abstract Rubber blending has been widely used to improve various properties in finished rubber products. The purpose of this paper is investigate the effect filler size, type, concentration, and surface treatment on mechanical, swelling, dielectric, morphology ethylene propylene diene (EPDM)/styrene-butadiene (SBR) blend nanocomposites filled with alumina (Al 2 O 3 ) nanoparticles. Bis-(3-(trie...

in this paper, the measurement of the viscosity of zno in ethylene glycol, propylene glycol, mixture of ethylene glycol and water (60:40 by weight), and a mixture of propylene glycol and water (60:40 by weight) and the thermal conductivity in ethylene glycol and propylene glycol as base fluids in the range of temperature from 25 ºc to 60 ºc are investigated. the results indicate that as the tem...

Abstract A novel manufacturing tool called sandwich flexible elastic grinding wheel is developed to achieve high material removal rates and machined finish of a mould steel. This made aluminium matrix, ethylene propylene rubber layer abrasive layer. Ethylene has great elasticity produces deformation when contacting with the workpiece. With existence an layer, rigidity at small scales allows occ...

Cyclopentadienyl-titanium complexes containing –OC6H4X ligands (X = Cl, CH3) activated with methylaluminoxane (MAO) were used in the homo-polymerization of ethylene, propylene, 1-butene, 1-pentene, 1-butene, and 1-hexene, and also in copolymerization of ethylene with the α-olefins mentioned. The -X substituents exhibit different electron donor-acceptor properties, which is described by Hammett’...
