“…In this work, it is assumed the solubility parameter of the HNBR used here is 19.3 MPa 0.5 , i.e. the midpoint of the range mentioned and well within the range reported in literature for similar HNBRs (17.8e20.69 MPa 0.5 [29], 17.9 MPa 0.5 [30], 19.7 MPa 0.5 [31] and 19.9 MPa 0.5 [32,33]). Of the solvents investigated here, it is clear that chloroform gives the highest saturation swelling for the HNBR, and the test solvent mix does not give a very strong swelling of this HNBR.…”

a b s t r a c tThe effect of ageing in a sweet oil environment on the tensile properties, apparent crosslink density, CO 2 diffusion and Shore hardness of a typical carbon black reinforced hydrogenated nitrile butadiene rubber (HNBR) is presented. Different ageing conditions yielded materials with different properties, attributed to varying degrees of apparent crosslinking. These results showed that, with increasing apparent crosslink density, tensile stiffness and hardness increased, while CO 2 diffusivity and saturation swelling in chloroform decreased. The relationships between these properties suggests that geometry independent tests (such as solvent swelling) may be performed on parts retrieved from service in order to predict properties (such as tensile stiffness or gas diffusion) which cannot normally be measured on retrieved parts due to geometrical constraints.

“…Therefore, we introduced the Hansen solubility parameters (HSPs), which were first introduced by Hansen, who divided the Hildebrand solubility parameter into three components which represent the specific type of interaction, namely, dispersion interactions (δ D ), polar interactions (δ P ), and hydrogen bonds (δ H ), respectively . The theory of HSPs has been extensively used in classes of materials such as nanoparticles and pigments, organic semiconductors, polymers, in artwork conservation, and in solid-phase extraction . However, there are few researchers in the field of ILs …”

The solubility parameters of four ionic liquids (ILs), 1-ethyl-3-methylimidazolium methyl sulfate ([EMIM][MeSO4]), 1-butyl-3-methylimidazolium methyl sulfate ([BMIM][MeSO4]), 1-hexyl-3-methylimidazolium methyl sulfate ([HMIM][MeSO4]), and 1-octyl-3-methylimidazolium methyl sulfate ([OMIM][MeSO4]), were estimated using two complementary methods. The first is an inverse gas chromatography (IGC) method, which determined the Hildebrand solubility parameters of four ILs based on a series of formulaic calculations. The second is the Hansen solubility sphere method, which determined the Hansen solubility parameters (HSPs) of the four ILs based on solubility testing of four ILs in 30 pure solvents. The results showed that the Hansen solubility sphere method provides higher values of the solubility parameters, while the IGC method presents lower values. In addition, the miscibilities of ILs in various solvents were evaluated by the method of IGC, and the results exhibit good agreement with those derived from the Hansen solubility sphere method. It is confirmed that the IGC and Hansen solubility sphere methods can be used to determine the solubility parameters of the ILs and were useful for solvent selection.

“…In Figure 4b, it is clear that the uptake of melamine is intimately related to the said Hansen parameter. Such a quasi linear correlation could be interpreted as follows: a solvent with a solubility parameter matching that of the MIP is expected to swell the polymer 42 and thus to facilitate the fast diffusion of the template molecules towards the polymer artificial receptor sites where the template molecules get preconcentrated.…”

Picomolar Detection of Melamine Using Molecularly Imprinted Polymer‐Based Electrochemical Sensors Prepared by UV‐Graft Photopolymerization

Molecularly imprinted polymer (MIP) films of melamine were prepared by photopolymerization of vinylic monomers on diazonium‐modified gold electrodes. The gold‐grafted MIPs are specific and selective for melamine in either organic or aqueous media. The interferent molecules cyromazine and cyanuric acid were not recognized by the MIPs. The limit of detection was as low as 1.75×10−12 mol L−1 at S/N=3. Efficiency of melamine rebinding is related to the solubility parameter of the organic solvent or pH and ionic strength of the aqueous medium. It is concluded that diazonium salts permit to design robust electrochemical MIP sensors.
