Thermoreversible Gelation, Crystallization and Phase Separation Kinetics in Polymer Solutions under High Pressure
… of phase behavior, crystallization, gelation and phase separation kinetics of polymer solutions in dense fluids at high pressures. The miscibility and dynamics of phase separation were investigated in solutions of atactic polystyrene with low polydispersity (Mw = 129,200; PDI = 1.02) …

Morphology-Property Relationships in Semicrystalline Aerogels of Poly(ether ether ketone)
The phase diagrams for the thermoreversible gelation of poly(ether ether ketone) (PEEK) in dichloroacetic acid (DCA) and 4-chlorophenol (4CP) were constructed over broad temperature and concentration ranges, revealing that PEEK is capable of dissolving and forming gels in DCA and 4CP up to a weight …

The production of a lyotropic liquid crystal coated powder precursor through twin screw extrusion.
… powder precursor by exploiting Pluronic F127 thermoreversible gelation property to get powder precursor without granular aggregates or with less compacted granular aggregates. The highly soluble chlorpheniramine maleate loaded in Pluronic F127 solution coated MCC particles prepared through …

Synthesis, Characterization, and Properties of Tailored Functional Block Copolymers
… ABA triblock copolymers can be used for the thermoreversible gelation of 5CB. To this end, ABA and ABA’ triblock copolymers comprised of PS A-blocks and a cyanobiphenyl-functionalized PHS B-block with a high degree of polymerization were prepared by the combination of anionic polymerization, …

Crystallization Behavior, Tailored Microstructure, and Structure-Property Relationships of Poly(Ether Ketone Ketone) and Polyolefins
… acetone (DPA) was discovered as a novel, benign gelation solvent for PEKK, enabling heterogeneous gel-state bromination and sulfonation to afford blocky microstructures. The gel state functionalization process resulted in a blocky microstructure with runs of pristine crystallizable PEKK retained …
