Application of hard-core Exponential-6 intermolecular potential function to determine the second osmotic virial coefficients of polymer solutions was written by Peyrovedin, Hamed;Khorram, Mohammad;Shariati, Alireza. And the article was included in Polymer Bulletin (Heidelberg, Germany) in 2021.Safety of Isopentyl 3-methylbutanoate This article mentions the following:
The osmotic pressures of polymer solutions are related to their corresponding osmotic virial coefficients There are several exptl. methods to determine the osmotic virial coefficients However, these exptl. virial coefficients are restricted to the exptl. conditions. An alternative way of determining the osmotic virial coefficient is with the help of statistical thermodn., and unlike exptl. methods, because of its theor. basis, it is not restricted to limited ranges of exptl. conditions. The osmotic virial coefficients can be used to calculate the different properties of polymers and polymer solutions, such as the average mol. weight of the polymer (M) and the theta temperature In this work, for the first time, the second osmotic virial coefficients of a number of polymeric solutions are calculated using the Kihara and Exponential-6 intermol. potential functions. Furthermore, the hard-core Exponential-6 model, that we have proposed, is also investigated. Addnl., the mol. weights and theta temperatures of these solutions are determined using the calculated second virial coefficients and are compared to literature data. The results show that the recent hard-core Exponential-6 potential model is more accurate than the Kihara and Exponential-6 models and is applicable for calculating other properties of the polymers and polymer solutions In the experiment, the researchers used many compounds, for example, Isopentyl 3-methylbutanoate (cas: 659-70-1Safety of Isopentyl 3-methylbutanoate).
Isopentyl 3-methylbutanoate (cas: 659-70-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Safety of Isopentyl 3-methylbutanoate
