Poly(Styrene-block-IsoButylene-block-Styrene) ("SIBS") is a biostable thermoplastic elastomer with physical properties that overlap silicone rubber and polyurethane. Initial data collected with SIBS stent-grafts and coatings on metallic stents demonstrate hemocompatibility, biocompatibility and long-term stability in contact with metal. SIBS has been used successfully as the carrier for a drug-...

We report on two important advances in radical polymerization with reversible addition–fragmentation chain transfer (RAFT polymerization). (1) Electrochemically initiated emulsion RAFT (eRAFT) provides rapid of styrene at ambient temperature. The electrolytes and mediators required for eRAFT are located the aqueous continuous phase separate from low-molar-mass-dispersity macroRAFT agent mediato...

The monodisperse and controlled polymer nanoparticles have attracted much attention in academic and industrial fields. Due to small size and extremely large specific surface area, nanoparticles could be used to the fields of drug delivery system, microencapsulation, chromate graphy, catalyst, organic/inorganic hybrid materials, and templates for porous inorganic materials. The dispersion polyme...

Self-assembled polymeric micelles can be used as efficient particulate emulsifiers. To explore the relationship between the structure and the oil-water interfacial behavior of the micelle emulsifiers, a new type of amphiphilic random copolymer, poly{(styrene-alt-maleic acid)-co-[styrene-alt-(N-3,4-dihydroxyphenylethyl-maleamic acid)]} (SMA-Dopa), was synthesized, self-assembled into micelles, a...

BACKGROUND In clinical practice, contact dermatitis is a relatively common skin complaint, whose prevalence has increased in recent years. Study by patch testing is essential for diagnosis of contact sensitization. OBJECTIVES To study the prevalence of sensitization to different allergens in a standard battery and observe the influence of different epidemiological and clinical variables on co...

2-Dodecylthiomethylpyridine (DTP) was newly synthesized to study its extraction properties for precious metals. DTP was a selective extractant for palladium(II) and gold(III) over base metals. The loading test for palladium(II) showed that one palladium ion reacted with one molecule of DTP. The extraction rate of palladium with DTP was measured using a Lewis-type transfer cell at 303 K. The ext...
