Control of droplet size of polymer-diluent blends through thermally induced phase separation

Formation of microporous membrane of isotactic polypropylene in dibutyl phthalate‐soybean oil via thermally induced phase separation

“…With the increasing of DBP fraction in the mixed diluents, the interfacial tension between iPP and diluents increases, which activates the droplet growth of iPP‐diluents system. Similar results were reported by Kim and coworkers26, 27 in different systems.…”

Preparation of polypropylene microfiltration membranes via thermally induced (solid–liquid or liquid–liquid) phase separation method

“…The coarsening process has been interpreted by three different mechanisms: ostwald ripening, coalescence, and the hydrodynamic flow mechanism. All the mechanisms present that droplet growth is closely related to the coarsening time and viscosity . With the decrease in the weight ratio of myristic acid to diphenyl carbonate, the L–L phase separation region gets wider.…”

Diluent selection forNylon 11 andNylon 12 thermally induced phase separation systems

“…Literature data show that various polyethylene glycols are capable of forming L–L TIPS structures with Nylon 11, Nylon 12, and Nylon 6,6. In particular, PEG400 has been shown to yield L–L TIPS structures for all three polymers, but with cloud points well above 200°C for most polymer concentrations . These high temperature requirements make PEG400 a less desirable diluent.…”
