These values indicate for vinylene carbonate in the Alfrey-Price scheme a reactivity Q equal to 0.012 and a polarity e of 0.6. From the r1 and r2 parameters of the system vinyl acetatevinylpyrrolidone (0.38 and 0.44, respectively) the Q and e values of vinylpyrrolidone have also been ...
(ii) Physical properties such as polarity, solubility etc. can be varied by changing the pressure and temperature. (iii) The reactivity of CO2 itself is often improved dramatically under supercritical conditions [8], [9]. (iv) Separation from the reaction mixture is easy. One of the most ...

A reservoir’s wettability is affected by electrostatic interactions between the oil/water and water/mineral interfaces. A more water-wet condition occurs when the interaction between crude oil and the rock surface is repulsive, because both interfaces possess the same surface polarity. Conversely, an...
However, CaCO3 particles are very easy to aggregate, owing to their small particle size, large specific surface area and high surface free energy [11]. In addition, the surface of CaCO3 particles has hydroxyl groups that exhibit polarity and have obvious characteristics of hydrophilicity and ...
Unfortunately, the development of HCEs is limited by their high cost, viscosity and surface energy [32]. To overcome these problems, HCEs were optimized as localized HCEs (LHCEs) with a counter solvent, usually using a polyfluorinated ether with week polarity to have a special solvation ...
The decrease in the shear modulus of EPDM/CaCO3 compounds with the addition of the Geniosil XL 33 silane may occur due to two reasons: first, the acryloyloxy groups in the Geniosil XL 33 silane are polar, and its polarity is related to the strength of silane adsorption on the calcium car...
