Nanocomposites of poly(3-hexylthiophene) (P3HT) and nitrogen-doped carbon nanotubes (N-CNTs) have been synthesized by two methods; specifically, direct solution mixing and in situ polymerization. The nanocomposites were characterized by means of transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray dispersive spectroscopy, UV-Vis spectrophotometry, photoluminescence ...

The in-situ formation of dispersed polyaramide whiskers during melt processing of polymers represents a new route to thermoplastic and elastomeric organic microcomposites. When N-(p-aminobenzoy1)-caprolactam (PAC) is injected into melts of high molecular weight polyamide-6 or dihydroxy-terminated poly(oxytetramethylene) liquid rubber, stable dispersions of polymeric whiskers are formed. At temp...

Conjugated polymer nanoparticles, produced by in situ colloidal Knoevenagel polymerization, show advantageous properties (bright emission, colloidal/chemical stability and mesoscopic size range) that allow the successful in vivo application to real-time sentinel lymph node mapping in a mouse model.

A novel method that selectively polymerizes pyrrole on the silica surface without inducing polymerization in bulk solution is developed, which is based on in situ generation of the NO(+) ion as an oxidant at the silica surface.

Indium trichloride, benzyl alcohol, and triethylamine (without an added 'directing' multidentate ligand) generate a catalyst in situ for the room temperature polymerization of D,L-lactide affording highly heterotactic polylactide of controlled molecular weight and narrow molecular weight distribution.

Polymerization processes with high reproducibility, traceability, and nontoxic compounds are required for biomedical applications. Here an automated solvent-free polymerization of hyperbranched polyglycerol has been established on a multiple-hundred gram scale. Performed is anionic ring-opening multibranching (ROMB) slow addition glycidol. The approach avoids commonly used organic solvents duri...

Film forming, stable hybrid latexes made of methyl metacrylate (MMA), butyl acrylate (BA) and 2-hydroxyethyl methacrylate (HEMA) copolymer reinforced with modified multiwalled carbon nanotubes (MWCNTs) were synthesized by in situ miniemulsion polymerization. The MWCNTs were pretreated by an air sonication process and stabilized by polyvinylpyrrolidone. The presence of the MWCNTs had no signific...

High throughput screening (HTS) of a 205 member Schiff base salicylaldimine ligand library derived from salicylaldehydes bearing bulky ortho-substituents, i.e., 9-anthracenyl, 1,4,5,8-tetramethylanthracenyl or triptycenyl, reacted in-situ with (p-tolyl)CrCl2(thf)3, identified two new classes of highly active chromium based systems for the oligomerization and polymerization of ethylene, respecti...

N-vinylcarbazole (NVK) is proposed as an additive for acrylates thermal free radical polymerization (FRP) and epoxy thermal ring opening polymerization (ROP) at room temperature. The new initiating systems are based on a silane/silver salt/N-vinylcarbazole interaction, which ensures good to excellent polymerization. Moreover, the polymerization is much more efficient under air than under argon....
