Estimation of miscibility of polymer blends using the solubility parameter concept

Effect of entanglements in the microstructure of cured NR/SBR blends prepared by solution and mixing in a two-roll mill

“…Thermodynamically, the miscibility in polymer-solvent mixtures or polymer-polymer blends can be predicted if the values of the Hildebrand solubility parameters, d, of their components are similar [34][35][36]. At room temperature, the solubility values of NR, SBR and toluene are: d NR = 16.6 MPa 1/2 , d SBR = 17.3 MPa 1/2 and d toluene = 18.3 MPa 1/2 , respectively [37].…”

Experimental and theoretical approaches to investigating the miscibility of anhydride‐containing copolymers and dextran

“…It has been found that for a greater number of polymer mixtures than was previously suspected, regions of miscibility may exist. 29 This means that, although miscibility was observed only with high amounts of Dx according to the experimental results, it was strongly expected that when a small amount of Dx was added to the synthesized copolymer samples, a part of copolymer would be miscible with Dx. When the amount of added Dx was increased, the probability of establishment of less favorable interactions between Dx and related copolymers also increased because the Dx chains became more available for bonding, and hence, a trend that enhanced miscibility was observed with increasing Dx content, as can be seen from Figure 1(a-f).…”

Properties of materials as determined by inverse gas chromatography

“…Therefore, the solubility parameter and the Hansen solubility parameters are physicochemical parameters which enable estimation of type and interaction force, responsible for compatibility between materials. The solubility parameter and/or HSP can be applied in the description of the behavior of materials in real systems, including such phenomena as: miscibility, adhesion and wetting [49][50][51][52][53][54][55][56][57]. is focused on application of inverse gas chromatography for characterization of different materials.…”
