An amphiphilic aryl-ether AB2-type dendron(1)bearing oligo ethylene glycol(OEG)chains exhibited lower critical solution temperature behavior in aqueous solutions. In the presence of salting-out salts(Na2SO4, NaCl, and NaBr), cloud points 1 decreased linearly with increasing salt concentration. The slope linear decrease changed anion type order, SO42- > Cl- Br-. salting-in salts(NaSCN NaI), incr...

A new low melting temperature poly(aryl ether ketone) (PAEK) thermoplastic polymer (Victrex AE 250) was investigated through thermal and rheological analysis of films flakes. DSC assigned to evaluate the influence cooling rate on crystallinity transitions. Rheometry used assess its flowing behavior evaluation dynamic moduli complex viscosity in melted state. The relaxation times were found from...
