Synthesis and association behavior of cationic amphiphilic copolymers consisting of quaternary ammonium and nonionic surfactant moieties

Synthesis and characterization of the PEG‐based nonionic surfactants endowed with carboxylic acid moiety at the hydrophobic terminal

“…A similar bimodal profile of size distribution has been reported for PEG-based copolymes. 29,30 Yamazaki et al also reported the hydrodynamic diameter of 6.0 nm for PEG monododecyl ether, C 12 EO 25 . 31 Taking the reports into consideration, small and large diameters of about 6 and 43 nm might be attributed to a surfactant micelle and a secondary aggregation, respectively.…”

“…The hydrodynamic diameter was automatically calculated using distribution of the relaxation time. 29 The sample solution was filtrated with a PTFE membrane filter (pore size: 0.20 lm) prior to the measurement.…”

Treatment of aortoiliac chronic total occlusions: Guidelines and reality

“…Development of polymeric profragrances can overcome these drawbacks (1) and (2). 1, 18–20 When the polymeric profragrances are synthesized by copolymerization of hydrophilic and hydrophobic monomers, varying their feed ratio enables adjustment of properties such as hydrophilicity.…”

Aortic valve in valve insertion: A note of caution and a case for possible optimism

“…Recently, various types of ionic liquids1, 2 have been investigated as novel nonvolatile and nonflammable functional materials, such as ionic conductive materials and environmentally benign solvents (a reaction medium), playing an important role in the field of environmental chemistry. These characteristics have also prompted much research on the synthesis and properties of polymers with ionic liquid moieties or similar structures 3–19. With regard to stimuli‐responsive behavior, an upper critical solution temperature (UCST)‐type phase separation of sulfobetaine polymers in water was reported 20.…”
